God reminds people of what he had done already. Often we see this in the Scriptures, as in the Psalms of salvation history (Psalms 78, 105, 106, etc.) God retells his story, so that we can have confidence in him during our present trials. Since we are his people also, we can meditate on his mighty works and his purpose in them and live in our situations with a godly perspective. Whatever has happened to God’s people previously happened because of his prophetic word, precious promises, and solemn covenants.
Now, in this Servant Song, Yahweh leads them into the future, into what he will accomplish in and through his Son, who is his Servant. He tells them this before these things happen, so that they can recognize that this is the word of the Lord (Isaiah 44:6-8; 45:20-23; 46:9-10). God announces that new events will occur. These are the events of Christ and his new and better covenant that he has just declared (42:6-7). And so God’s people can expect greater things. This is what happened when Jesus Christ came, lived among people, taught us, died for sinners on the cross, was buried, was raised to life on the third day, ascended into heaven, and poured out the Holy Spirit on all who believe. The newness includes God’s ultimate triumph when he makes all things new (Revelation 21:5).
God’s announcement of these new events is intended to lift up the Lord Jesus Christ before us in our thoughts and ideas. God wants us to have a radical change of mind about the Lord Christ and to trust in him for the light and liberation of salvation. He wants us to have Christ as the center point of our relationship with him, instead of spiritual experiences, performance of rituals, activity in church programs, or obedience to commands. Christ is our covenant. For this reason the Father asserts his glory, the glory of the One who chose and sent the Servant, that we might have a higher view of the Lord Jesus Christ. Are you among those who have repented and believed? How does this glorify God? He is greatly praised in the salvation of his chosen people (Ephesians 1:3-14). God is also glorified when his people live in conformity with his plan rather than human opinions. Is Christ your functional covenant in the way you relate to God? Strangely, too many seem to prefer to relate to God through rituals or rules or some other supposed path of spirituality. The Lord Jesus is our great high priest and mediator (Hebrews 4:14; 9:15) and he is our covenant, and so the Father wants us to draw near to him through his Son (Ephesians 2:18). Don’t miss God’s way, because you’re too involved with what other people tell you.
Grace and peace, David
