You have all made promises; and kept them, but some you have broken. Maybe you didn't intend to break it, but when the time came to fulfill it, it simply wasn't in your power to keep it. Or, upon re-thinking it, you decided it wasn't a good promise, so you reneged upon it.And, you've had promises made to you; and they've been kept - some of them, but who has not been hurt by having a promise made, and then broken?

What parents have not heard their child exclaim at some point, "But you promised me!" Obviously, some promises are easier to keep than others. A mother told of overhearing a conversation between her two daughters. The younger child had had considerable difficulty in trying to learn how to know which shoe went on which foot. The older girl said to her younger sister, "Listen, I'm going to tell you something and I want you to remember it the rest of your life. Do you promise to remember this the rest of your life? Promise for as long as you live?" The younger child meekly said, "Yes." The older one said, "Okay. Here it is. Whenever you put on your shoe, if it hurts, you've got it on the wrong foot!" Now that's an easy enough promise to keep, but have you heard any of these and had them broken? "I promise I won't tell a soul." "I promise to love, honor, and cherish." "I promise to be faithful." "I promise to pay the bill." "I promise to never do it again." "I promise to not forget." "I promise to be there on time." "I promise you this is the truth."

Promises! Promises! What good are they if all you have is someone's word? They may be able to perform, or they may never intend to keep it. They may not have the power to do it, it may slip their mind, and on and on it goes. That's the problem with a promise. Sometimes the word of another is simply not enough. We need a guarantee!

Look at the problem with a promise.

The Promise And The Promiser

We Christians are people of promise. It requires faith to believe in a promise that is not immediately kept, and that is the lesson of this text.

Abraham and Sarah began a pilgrimage of hope when they left Haran. About all that Abraham had was a promise (Genesis 12:1-4a), a promise that the God who called him would make of him a great nation, that God would bless him, that God would make his name great, and Abraham himself would be a blessing.

But you can't be made into a great nation without descendants and you can't have descendants without having children, and Sarah was barren, and all this childless couple have is a promise that looks impossible. Abraham is already 75 years old and Sarah is 65. And they have a promise that God will make of them a great nation. If they had told us about it we would have thought: "They must have misunderstood. God must not have been speaking literally. Surely this is a Scripture that must be de-mythologized; it must have a 'spiritual application.' After all, 65-year-old women do not bear children, so either Abraham must get himself another, younger woman to bear him a child (Abraham thought of that and tried it), or they must adopt. But one thing is sure, this particular promise must not be taken literally. After all, God expects you do use good, common sense!"

But God did promise an heir to Abraham and he meant it. But how can you trust in a promise when the evidence against its being kept is all around you? That's Abraham's dilemma - and the same problem is often ours.

Abraham is called the "father of faith," but it is not a title that was easily earned. Abraham's faith is not a peaceful, pious, wishy-washy faith. His faith and conviction in the promise of God is hard-fought and deeply-argued.

The text opens with God's promises being re-stated: "Fear not!" Abraham has probably come to terms with his barrenness; is learning to live with it. Nothing was ever going to change. Then God shatters that kind of thinking with his "Fear not!" and then God repeats the promise. Abraham retorts and protests and argues about the delayed promise (vv. 3, 4). He tells God what God already knows (we do that a lot, too): "I have no offspring, I am childless, a slave in my house will be my heir." Abraham feels a lot of anguish over this. He had no son and a "reasonable substitute will not do."

Then God re-asserts his promise, shows Abraham the stars, but really offers him nothing more, nothing new, nothing except his Word! After this discussion, all Abraham has, is still just a promise, just a Word. He has nothing in writing (AT&T dares you to ask their competitor to put their claims in writing), no proof, no guarantee. Now the test of faith really begins. Now Abraham must decide if God is God, if his Word is good, if - after all this time - in spite of the evidence to the contrary, if he can count on this promise. And Abraham believed! No wonder he is called the "father of faith!"

Abraham decides that God, not the circumstances, make the promise believable. He decided that the same God who makes stars can also make a son for an old, barren, childless couple. Abraham didn't decide to believe because he felt new life in his loins, nor because Sarah came and told him she was experiencing morning sickness, nor because a new fertility drug for older women had just been approved by the FDA. He simply believed he could rely on the promise of the Promise-Maker.

God has given us promises, too - thousands of them - in his Word. I haven't checked them all out, yet, but the ones I've tested and tried I have found to be unshakably certain. God promised: "Come to me, all ye who are weary and heavy laden, and I will give you rest." I came and he did. He said, "If we confess our sins he is faithful and just to forgive our sins and to cleanse us from unrighteousness." I did and he did. Jesus promised, "I will send the Holy Spirit upon you." He did. He said, "The Lord will give peace to his people." I have found that he does. The Word promises, "Delight yourself in the Lord and he will give you the desires of your heart." It's true, he does. He promised, "Seek ye first the kingdom of God and his righteousness, and all these things shall be added unto you." It's a fact. He assured us, "Lo, I am with you alway." He is."

I keep finding, or hearing, or reading a promise, and he keeps making it true. I have never known one of God's promises to fail.

These days of Lent remind us that God promised to send to the world a Messiah, a Redeemer, his Anointed One. And for six weeks we look again in wonder at that fulfilled "Word that became flesh and dwelt among us." We took that promise made incarnate as God became reality in that little baby boy born in Bethlehem's barn and we nailed him to a tree. Did Isaiah say more than he realized when he said, "He was pierced for our transgressions, he was crushed for our iniquities, the punishment that brought us peace was upon him, and by his wounds we are healed (Isaiah 53:5)." Can we ever again doubt any promise God has made when we see the promised Savior hanging before us in the throes of death as in agony he fulfills God's Word?

So, as people of faith, we make the assumption that because of who the promiser is - none other than God himself - that we can believe it. Abraham made the basic assumption that God was God, that his Word was enough, and that assumption became an unshakable assurance. Helmut Thielicke said, "Taking God seriously means taking him at his Word and giving him the chance to act the way he has said he will act."

A woman came up to an evangelist after hearing him preach, and said that she could not understand salvation. The preacher said, "Mrs. Franklin, how long have you been Mrs. Franklin?" "Why, ever since I was married," she replied. "And how did you become Mrs. Franklin?" he asked. "When the minister said, 'Wilt thou have this man to be thy wedded husband,' I just said 'Yes.' " "Didn't you say, 'I hope so,' or, 'I guess so,' or 'I'll try to'?" asked the minister. "No," she said, "I just said, "I will." Then the evengelist pointed to God's Word and said, "God is asking you if you will accept his Son. What will you say to that?" Her face lighted up and she said, "Why, how simple it is! Isn't it odd that I didn't say 'yes' a long time ago?" This is the simple faith in God's Word that is called for. God has promised that if we come in repentance and faith, that he will receive you for Christ's sake. Trust it, count on it, try it, believe it. Remember, you can never break God's promises by leaning upon them.

The Promise Delayed

The problem with a promise is always the delay, the waiting. We have lived with so many broken promises made by humans that we've come to expect the same from God. Some months ago I preached a revival. In the dining room of the motel where I stayed while I was there, was a sign. It read: "We promise friendly and courteous service at reasonable prices. If for any reason we fail to live up to this promise - please don't tell anyone!" But God lives up to his promises. He does not break them. But he does sometimes delay. To wait a very long time is a strong theme in this text. Abraham has no heir, and in spite of having a promise, he must wait still longer.

We are not accustomed to waiting. We don't like to wait on the phone, we resent being put on "hold," we'd rather not wait in a long line, we don't want to wait for a diet to show its effect, we don't like to wait our turn. We are a fast-food, fast-service, fast-car/plane/boat people and are impatient when we have to wait. We now have fast, drive-through viewing for the dead so we don't have to wait. "Well, I'm not going to wait any longer," is a phrase you hear nearly every day of your life. So, when we deal with the promises of God we are equally impatient and are prone to conclude if the answer is not given now, it never will be.

But a promise is a gift, a grace from God, and gifts cannot be forced nor hurried. Our futures stay in the hand of the God who gives them.

God's move toward Abraham was free and unconditional. Abraham needed only to trust, and he did. "He believed God, and God credited it to him as righteousness (v. 6)." It is only an unsure faith that wonders about delay. An unsure faith questions "When?" and "How?" A faith in the promise of the divine Promise-Maker believes and waits.

We cry, "O Lord, how long?" How long until I am well again, how long until my children are saved, how long until my marriage gets better, how long until you find me a job/husband/wife/house? And that's the test of our faith, just as it was for Abraham. We are like little children when we have to wait. A family was taking a trip by car, some distance away. Knowing the impatience of their young son, the parents cautioned him as they got into the car, "Now we will get there as soon as we can. We will get there. But don't keep asking when we are going to get there - understand?" After traveling some miles, from the back seat of the car the boy ventured this question, "Will I still be alive when we get there?"

We run by clocks and calendars, by schedules and timetables, so we assume God does, too. And we want him to tell us when, what time, what day, what year - forgetting that God does not limit himself to our puny plans and schedules. He has eternity and our days and minutes and years are not binding to him. Of course we argue and say, "But God, if you don't do it now, or by Tuesday, or next year, it will be too late." But that is putting human limitations upon God, saying, "He can't fix it," except in our time frame.

Abraham was 75 and Sarah was 65 when God gave them the promise - how easy it would have been for Abraham to say to God, "You'd better hurry - Sarah's not getting any younger. It's impossible now, but it's getting more so every day." Amazing, when you think about it, this "father of faith" had such simplicity of trust in the promise. Note the three words, "Abraham believed God." Don't you wish it could be written of us, "Barbara believed God." "John - Joe - Betty - your name - believed God." Habakkuk, the prophet, has some good words on this, "If it seems slow, wait for it; it will surely come, it will not delay (Habakkuk 2:3)."

The Promises Are Worth Waiting For

Let us never forget: the promises of God are worth waiting for! In a rather restrained fashion, our text suggests (vv. 17, 18) that somehow the mysterious and unseen presence of Yahweh is engaged in this action. Abraham has prepared a sacrifice of a heifer, a goat, a ram, a dove, and a pigeon to offer to God. It is then that the Lord comes to Abraham. He has a mysterious firepot with a blazing torch and the fire moves among the pieces of the sacrifice that Abraham has placed upon the altar. This is a curious, old, ritual act which suggests a solemn, weighty, binding of the two parties to each other. God is here making a covenant with Abraham, renewing again his promise of an heir and land.

This text makes us ask two large questions: Can Abraham trust? Can God be trusted? The answer in both cases is a resounding "Yes!" God put flesh on his word and gave Abraham a son. He had to wait for it - he was 75 years old when he first got the promise (Genesis 12) in Haran. Now, 25 years later, when he is a centenarian, the promise is fulfilled and Isaac is born.

God is always doing such things with his promises. God finally put flesh on his Word, and the promise was fulfilled, centuries later, when God gave the world Jesus. He always is true to his Word.

Lent's cross-bound journey is another reminder that the promised Redeemer came and lived and died that we might know God as Father; might have forgiveness of sins, and have life everlasting.

I haven't checked out all of the promises of God yet. But each one that I have ever relied upon has proven true and faithful. But there are still other promises God has made that are worth waiting for. I still claim them, though they haven't come to pass yet, but God's past record absolutely convinces me that he can be trusted for the future ones.

So, when Christ says, "I will come again," I believe it. No matter how long it is until it happens, I still believe in the second coming. He said, "I will go and prepare a place for you, that where I am, ye may be also." No matter when I die, I firmly believe I have a home in heaven waiting for me. He said, "Train up a child in the way it should go, and when it is old it will not depart from it." That promise has been parti,ally fulfilled for me, but I believe it will happen. God will not let all the toil, teaching, prayers, tears, and love we give our children be wasted. I believe God.

The Problem Is Not In The Promise-Maker, But Receiver

We cannot just "decide" one day to have faith. It doesn't work that way. Abraham did not move from protest to confession and faith by persuading himself, or by talking himself into it. He simply accepted the disclosing Word of God. We, too, become practitioners of faith in all of our hopelessly, impossible situations by knowing the two things that Abraham came to know: God could be trusted, and he would trust God. That is why we can so lustily and confidently sing the lines of the familiar song, "Standing on the promises that cannot fail, When the howling storms of doubt and fear assail, By the living Word of God, I shall prevail; Standing on the promises of God!"
