For Christ also suffered for sins once for all, the righteous for the unrighteous, in order to bring you to God. He was put to death in the flesh, but made alive in the spirit, in which also he went and made a proclamation to the spirits in prison, who in former times did not obey, when God waited patiently in the days of Noah, during the building of the ark, in which a few, that is, eight persons, were saved through water. And baptism, which this prefigured, now saves you—not as a removal of dirt from the body, but as an appeal to God for a good conscience, through the resurrection of Jesus Christ, who has gone into heaven and is at the right hand of God, with angels, authorities, and powers made subject to him. (1 Peter 3:18-22, NRSV)
Baptism saves us, not as a washing away of dirt, or sins, but as an appeal to God for a good conscience. God claims us as His own children in the waters, and unites us to the death of Jesus. And if we are united in His death, then we will be reunited in His resurrection.
We are made alive, not by our own doing, but through the gift of God. The naming and claiming as His children. Not in the flesh but in the Spirit.
God with us, makes us alive, and gives us an abundant life.
