Isaiah 42

1 The Messiah would have these characteristics: He would be a servant, He would have God's Spirit, and He would open the door for the Gentiles to be saved.
2 The Messiah would not shout in the streets to gather people together. Jesus, in fact, typically preached outside cities. When He was in a city, He usually taught in homes, synagogues, or the Temple.
3 The Messiah would not come to judge at first. The bruised reed and smoldering wick represent people injured and suppressed by their sins. Instead of killing them off, He would try to bring them back to health. However, there would be a day when He will condemn those who have not responded to Him.
4 This appears to refer to the Messiah's death. Although some translations use the word "discouraged," the Hebrew word means crushed, bruised, and oppressed. In other words, He would suffer the same way as the reed and wick in the previous verse. Yet, that will not be the end, because the whole world (even the distant coastlands or islands) would wait in expectation of the fulfillment of His words.
5 This interesting verse speaks of God's creation. The first phrase speaks of God stretching out the heavens. This would indicate that the universe is bounded. This should not be surprising because only God is infinite. The second phrase speaks of the physical earth being "hammered out" and "stamped," similar to what a metal worker does. The third phrase reiterates the Genesis account of God giving His own breath to humanity.

The overall idea is this: since God has done all these great things, He will send the Messiah as He has promised.

6 The Messiah would be known for His righteousness and for being led by God. He would be given as the fulfillment of the Promise and the Law of the Old Testament. However, His ministry would go beyond Israel as a saving light for the Gentiles as well. This would have been a provocative statement since the Israelites felt that God would save only them.
7 While the Messiah would prove to be able to heal the physically blind, His purpose was to help the spiritually blind to see. One part of His mission was to tell people that God exists and cares about them. Another part of His mission was to free people from the prison of, and ultimate punishment for, sin.
8 The Messiah will share God's glory, but no other person, creature, or thing deserves the honor, respect, and praise that is due God.
9 God will fulfill the Old Covenant and begin a New Covenant with the coming of the Messiah. The First Covenant was characterized by faith expressed in obeying the Law. The Second Covenant would be characterized by faith in the Messiah.
