The Lord liberated his people from oppressive bondage in Egypt. They were now free to enter into a covenant of love with their God. Israel constantly looked backwards to this great liberating event reminding them that their God is the One who set them free from oppressive bondage. Later in their history, through Isaiah, the Lord pointed them forward to a new exodus event. He would act again to liberate them from oppressive exile in Babylon and also from even more oppressive powers. And in this new exodus Israel’s covenant God will prove to be the God of all peoples.
At his transfiguration Jesus spoke to Moses and Elijah about his “departure” which he would accomplish at Jerusalem. The word translated departure in Luke is exodon so they were talking about his “exodus”. The death of Jesus is the new exodus that God promised through Isaiah.
In this new Exodus the lowly servant of the Lord liberates us from all the powers that oppressed us. Through him we are free from sin, death and all the dominion of darkness. And that means we are free for a new covenant of love with God sealed with Jesus’ blood. Within this new covenant we are free to enjoy life in the promised land of participation in the very life of the triune God. Furthermore, within this communion of love we anticipate the day when the creation itself will be liberated from its bondage to decay and brought into the freedom and glory of the children of God.
