1. God destroys as well as preserves [Isaiah 42:14]
Luther says that God is to be both loved and feared. The same God of compassion who is eager to show love to those who turn to him is equally determined to root out and destroy evil. Isaiah is warning us not to be lulled to sleep by thinking only of the kindness of God. He who shows patience toward our waywardness will eventually cease to overlook unatoned sin and will destroy. He holds all the power of the universe in his hands to work his ends. Our eternal destiny is for him to determine. Are we tempting God by clinging to things he opposes? Remember God has said, "I will destroy." The time to repent and make peace with him is now.
2. Christ will restore sight [Isaiah 42:16]
A blind beggar walking down a street on a day in spring carried a sign saying, "It is April, and I am blind." How pitiful that he was blind at any time. But on a spring day it was even worse; he could not see the newly formed leaves on the trees, or the beautiful flowers blooming on every hand. He could not see the earth bathed in sunshine or the glow of a sunset in the western sky. But another blindness is even worse. It can come to those who have retained their physical sight. There is a saying, "None is so blind as he that will not see." When Isaiah talks of the blind he includes everyone who does not have spiritual insight. Children laugh at the phrase, "I see, said the blind man." Yet it is true that the physically blind can see many things which the person with sight overlooks. So God promises to help us in our spiritual blindness. He will show us the path of righteousness, reveal opportunities to serve our fellow man, to improve ourselves, and to see the Christ who is hidden from those who do not believe in Him.
3. Idolators shall be ashamed [Isaiah 42:17]
Idol worship seems like something out of the long past. It brings to mind visions of ignorant people in an earlier age bowing down before a statue which to them is their god. So this verse does not seem to apply to the one who reads it today. Here is where we deceive ourselves. Idolatry is a very subtle thing. It was said of Sampson that he did not know when the Lord had forsaken him, and thought he could go on in strength as he had before. So idolatry creeps upon anyone who is not alert. It is so easy to cater to oneself; to want fame and fortune so badly that we slowly let these desires come between us and God. Beware lest great shame come upon you because idols of today have subtly replaced God in your objectives and desires.
4. God will be praised for his law (Gospel) [Isaiah 42:21]
Our age is one of much disdain for God’s law. The ten commandments are regarded by many as out of date. They are as foolish in disdaining God’s rules and thinking they have outgrown them as was a certain sailor. The captain had pointed out the north star before turning over the wheel to the young seaman. He told the young man to steer constantly toward that star. The captain then took a nap and upon awakening found that the ship was not on course. When he questioned the young sailor what had gone wrong, he was told, "I have sailed past that star, show me another one." No one can sail past the ten commandments. They remain as up-to-date as the day’s news announcements. God has chosen to give honor to his eternal rules, whether they be revealed in the Ten Commandments or in Jesus Christ. The wise will realize the worth of God’s laws and strive to obey and honor them.
