All our sins are destroyed in the waters of baptism. The one who emerges from the baptismal pool after being submerged in it joins Jesus in his ascent out of Sheol into the New Creation. The resurrection of Jesus is not the resuscitation of a corpse or the mere vindication of a just man. It is totally a new way of being. God's answer to Jesus' double-bind is to bestow upon him complete and unlimited participation in the Father's glory.
Creation is totally new in the light of the resurrection.
The Sabbath belongs to the old world of sin that has passed away in the destruction of Christ's body on the cross. The New Creation, the eighth day, the day after the Sabbath, is the first day of eternal life in union with Christ, a day that will never end. This new life is the significance of Jesus' death, his descent into Sheol and his resting in the tomb. The revelation of the enormous energy of the New Creation awaits the moment of his resurrection.
