Because we are joined to Jesus's death, we are also given new life through the power of Jesus's resurrection. None of this is accomplished by our efforts. It happens with the power of God's Spirit that moves over the water when God's word is spoken. Baptism and its fruit in our lives are gifts from God. We are reborn as children of God in baptism.
Baptism is a one-time experience in life.
But its' results are life-long. After our sinful nature is washed away, we respond to God's gift by living in loving relationship with him. When we affirm our baptism, we are saying yes to what God has done for us. We are promising to continue to live in this relationship God established with us.
