V.1-4 Three servants of God are mentioned in Isaiah (1) David (Isa. 37:35); (2) Israel, as a nation (Isa. 41:8-16) and other places; (3) The Lord, (Isa 42:1-12) and all of chapter 49. Do you recognize that lowly life which was never in a hurry? God always had His beloved Son in mind. Turn to Matthew 12:18-21, it helps you to understand these verses. Just think that God became such a lowly Servant. The Lord Jesus is the Servant, and the Lord Jesus is God.
V.7 We are never told in the Old Testament of one Israelite, who had been born blind, receiving his sight. The Lord Jesus was the first one who brought sight to the blind (Mark 10:46). Written about 600 years before He came to earth.
V.5-12 These verses all refer to the day when Christ shall come again in His glory (see “E” on your chart).
V.13-16 What the Lord will do during that time.
V.17-25 Everyone who turns away from the Lord to other gods — this might be done when we set our minds to find pleasure in the world — will end up in disappointment.
V.24 Here it tells us that God controlled what happened to Israel. He allowed the robbers to come and rob them. So if we turn to other things, and forsake the Lord. He allows us sometimes to get into trouble. And all because He loves us so much.
