The spiritual genius of the lectionary is on display when the water and flame poem of Isaiah 43 in the Old Testament is connected with Luke’s account of Jesus’ baptism in the New Testament. By making this connection, we are shown that God’s promise to be with us as we pass through rivers and waters, through fire and flame, is fulfilled, as all the promises of God are, in Jesus. For Christ Jesus is the one who joins us in the waters of baptism and the one who purifies us in the baptism of fire.
