Every pastor would like to have the kind of response to a sermon that Peter had on the Day of Pentecost.  Three thousand people were added to the church after Peter had finished.  Even more importantly, three thousand people had their lives profoundly changed. For most of them it was a change that would make them a pariah in their community and even in their own family. Some would go on to die for their faith. Their faith was no surface affair. It involved a complete commitment to the work of God.

There is a tombstone in Scotland on which are carved these words about a man named Angus McDonald: “He was not a particularly religious man, but in all other respects he was an ideal churchman.”

How do you do that--be an ideal churchman without being particularly religious? I am not sure exactly, but I suspect that could be said of many who fill the pews of Christendom.

You are familiar with the famous Leaning Tower of Pisa. It leans almost twenty feet out of perpendicular.  Somehow, when the architect was planning that tower he designed a tower that reached a height of l79 feet but had only a ten foot foundation.  No wonder it leans! 

To me, the tower of Pisa is like a person who is “not a particularly religious, but in all other respects an ideal churchman.” He or she has an inadequate foundation.

Notice how the three thousand who heard Simon Peter that day responded to his preaching.  They came to Peter and the rest of the apostles and asked, “Brothers, what shall we do?”

This is a critical point in their lives. Will they be “ideal churchmen, but not particularly religious?” Will they have a tiny foundation under a tall structure? “Brothers,” they ask. “What shall we do?”

Notice what Peter tells them to do, “Repent and be baptized, every one of you, in the name of Jesus Christ for the forgiveness of your sins. And you will receive the gift of the Holy Spirit.”

Did you catch the sequence? “Repent . . . Be baptized . . . Receive the spirit.” These concrete steps constitute a proper response to the good news of Jesus Christ.  These are the essentials of a vital faith.  

Let’s begin with repentance.  This is a word that will fall on many deaf ears. Not many people nowadays want to hear about repentance.

I appreciate what former San Francisco Giants manager Dave Bristol once said.  His team was in the middle of a terrible losing streak.  Bristol said to them, “There will be two buses leaving the hotel for the ball park tomorrow.  The 2:00 o’clock bus will be for those of you who need a little extra work.  The empty bus will be leaving at 5:00 o’clock.” In other words he was saying, everybody needs a little extra work. 

That’s true of us as well. There are many of us who feel that repentance is for others.  We are like the six-year-old girl who said to her mother, “The number one problem in the United States is climate change. I read that in my Weekly Reader.  Everybody,” she continued, “knows that the number one problem in the United States is climate change--everybody but our preacher.  He thinks that it is sin.  I feel that is just because he is a preacher.”

Could I say that if there is a man-made component to a heating earth, sin is definitely a part of that? God has made us stewards of this earth, but we have not taken care of our environment. So it is with nearly every problem on earth. Sin is involved . . . and the sad thing is that most of us do not want to acknowledge our need of repentance.  

Even more disturbing are the many people who flaunt their lack of moral discipline.  They advertise their flaws on bumper stickers and provide daily fodder for Hollywood gossip columnists. 

I believe it was Tallulah Bankhead who once said, “My heart is as pure as the driven slush.”  I don’t know about Miss Bankhead’s personal life, but there are many people who smirk at the idea of repentance. 

Every pastor knows that in counseling very few people express regret for their sins.  Many are sorry that they were caught, but few are willing to admit that they have done something wrong.  And yet, as we look at the torment in our society today, the wreckage of home and family life, the destruction of persons by alcohol and drugs, the scandals that have come from our highest echelons of business and government, we are led to believe that repentance is indeed a universal need. 

I read recently about the death of an enormous tree in Colorado.  It was such a large, old tree that some experts believe it was probably a seedling when Columbus discovered America.  It was only half-grown when the Pilgrims landed at Plymouth Rock.  Close study reveals that the tree was struck by lightning some fourteen times. 

However, lightning did not destroy that tree. Cold Colorado winters did not destroy it.  Age did not destroy it.  Avalanches did not cause it to budge.  Fire did not bring its final demise. No, according to the news report, this enormous tree was finally overcome by beetles.  Little bugs so small that anyone could crush them between finger and thumb, and yet these little unobserved beetles brought down this mighty Colorado tree. (1)

That is a parable of our lives.  As Solomon once noted, it is the little foxes that eat the vines (Song of Solomon 2:15). 

The late Norman Vincent Peale was not a judgmental pastor.  He was known, of course, for his “power of positive thinking.” 

I was interested to read about an interview which he had with a very prominent New York City businessman.  The businessman came into Dr. Peale’s office and laid out a tragic tale of confusion, frustration, and misplaced values.  He painted a dark picture indeed.  When he finished describing his misspent life, he asked Dr. Peale, “What do you think I should do?”

Norman Vincent Peale said, “Well, I have a solution for you.  It is simple and you are a very sophisticated and intelligent man.  I doubt that you would want to hear it.” 

The man said, “I think I would like to hear it.” 

Then Dr. Peale said, “No, I don’t believe you would.  It is too simple.” 

Again the man responded, “I want you to tell me.”

Dr. Peale said one more time, “I really don’t think you want to hear it.”

After a while the man became angry.  “Look,” he said, “tell me what your answer is.” 

Dr. Norman Vincent Peale answered like this, “What I really think you need to do is to get down on your knees and tell God that you are a sinner and ask God to forgive you and change you.” 

That wasn’t what that man wanted to hear, but it is what many of us need to hear about our lives.

There is a universal need for repentance.  Perhaps that is your need this morning.  The people who heard Simon Peter’s sermon asked, “What shall we do?” Peter responded, “Repent.” That is always the first step in Christian faith. 

The second step in Christian faith is to be baptized in the name of Jesus Christ.  For those of us who have already been baptized, Peter might say to us that our great need is to reaffirm our baptism daily.  We have already had the water applied at some time in our lives, but we continually need to be re-baptized within.  We continually need to take that step of faith daily that says, “I come with my sinfulness and shame and I yield myself to Christ.  I ask him to cleanse me and to help me to be born anew in faith.” 

I understand that there is a practice in Poland called “Wet Monday.” It is celebrated the day following Easter.  On this occasion of “Wet Monday,” Polish young people soak their friends and unsuspecting parents with water.  I don’t want to give our young people any ideas for next Easter.  Nevertheless, in Poland it is not uncommon to see young people standing out in their yard on the day after Easter with water hoses or walking down the sidewalks with buckets of water ready to douse somebody. 

“Wet Monday” has no religious significance that we know of.  It is mainly a day of pranks and good humor, but some believe that it is a holdover of an ancient religious practice (2).  

Actually I find the symbolism very appealing.  A Wet Monday following Easter--a re-baptism following the celebration of the resurrection--would be a good idea.  Repent and be baptized. 

The baptism that Peter calls for is to be more than a superficial experience.  A great tragedy for many of us who have been baptized and who are pretty good church people, is that we have been only partially baptized. We have not allowed Christ to rule supreme over all of our lives.  That is why we are continually in need of this reaffirmation. 

Robert Lobert once wrote a little booklet titled “My Heart, Christ’s Home.”  In this booklet he describes a disbeliever as someone for whom Christ is on the outside knocking, awaiting entrance. 

He also tells about one kind of believer who has allowed Christ into his house, but who has offered him only the chair in the hallway.  There the Lord sits dressed in his overcoat, holding his hat in his hand.  He sits waiting minutes, then hours, days and even years to have access to the rest of the house.  Meanwhile the host carries on business as usual while Christ sits out in the hallway. 

You get the picture.  The baptism that you and I need is a baptism of the whole person--all of our attitudes, all of our actions, all of our dreams and all of our desires. Christian faith is more than a “just inside the hallway experience.”

You may know the story of Constantine, the Roman Emperor who became a Christian.  Having taken this step, he wanted everybody else to become a Christian as well.  He took his soldiers out into the river to have them baptized. 

As they were baptized, however, he had them hold their right arms out of the water.  He wanted them to become Christians, but he didn’t want them to become so Christian that they would quit killing people with their swords. 

Is that the kind of baptism that characterizes your life? Has something been held out?  Do you need to make a reaffirmation of your faith?  Do you need to allow Christ access to more of your life than you have been permitting him in the past?  Repent of your sins. Reaffirm your faith. 

Finally, Peter says to the new believers, receive the gift of the Holy Spirit. 

There was a young lady who worked in an enormous factory, one of the largest factories of its kind in the world.  One day she confided to her pastor that she would have to quit. 

“What’s the matter?” he asked her. “Doesn’t the factory have enough orders to keep you going?”

“No,” she replied, “It’s not that.  They have more orders than they can fill, but they haven’t got enough electricity to keep all of the machines going at once, and my machine has to lay idle part of the week.  I lose so much time and pay.  The trouble is that they have more machinery than power.”

That can happen to us--more machinery than power. We need power if we are to deal with our lives so that we are kept in the way that leads to life.  We need power--power to make the changes necessary for us to be all God created us to be.

Tom Harris, the famous psychiatrist, who wrote that enormously successful book, I’m O.K., You’re O.K. says that there are three reasons why people change.  First, people change when it is more painful to remain as they are than to change. 

Perhaps you are in a job that is very painful to you.  You cannot imagine being in that job for the rest of your life.  So, you make a change.  Why? Because it is more painful to stay where you are than to change. 

A second reason for change, according to Harris, is when we find ourselves at the point of despair.  Perhaps we suddenly come to the realization that we are about to lose our marriage, our job, our health.  At that point we may change.  You have heard people say, “I had to reach rock bottom before I could take hold of my life.” 

Harris believes that there is a third motive for change, however.  He calls it the “Eureka Stage.”  That is, some people change because they discover--much to their surprise--that there is something better that they have been missing.  Of course, this is the message of the Gospel.  There is a richer, fuller life that is available to all who will receive it. 

Those who heard Peter preach his great sermon knew that they had found something that would make their lives more joyous, more purposeful, more livable. “Eureka!” This is it.  “What shall we do?” they asked.

“Repent,” Peter answered. “Be baptized. Receive the Holy Spirit.” You and I need to take each of those steps daily in our Christian walk.  They are the key to a life that is full, rich, and eternal.
