Baptism is a mark of our new identity, based not on the power of tribe or family, education or status, race or gender, but on the power of God’s promises. This is the gift of an identity that bears the marks of God’s saving power. Infant baptism especially conveys this – emphasizing that before we have the power to do anything, God’s power is for us. Similarly, in adult baptism we enter into the death and resurrection of the One who alone has power to triumph over sin and death. God’s power, evident in baptism, is the power both to promise and to be faithful, to create and re-create, to name and rename, to die and to rise.
