The Baptism again?

Diocese of East Tennessee: Sunday Lectionary Readings: "Today's readings affirm God's promise of continuing relationship. In Genesis 9, life begins anew, sealed by God's promise to all creatures and confirmed by the rainbow. The author of 1 Peter explains that we are saved through the cleansing water of baptism. In today's gospel, Jesus' 40 days of temptation in the wilderness end with the proclamation of God's good news."

How is this different from the last time we had the baptism narrative? The inclusion of the wilderness pericope is the obvious place to focus. I understand that the 40 days in the wilderness is much of the basis for lent. But the other readings have a definate baptism motiff. In focusing on the wilderness, do we loose the interplay of the readings?
