Romans 6:1-11
Baptism's Good News - Christ's Death and Resurrection are Yours

Baptism is the visible symbol of God's oath to all who trust in Jesus:

In Christ, you died.  

Your rebellion, your failures, your sin, your guilt, your punishment, and your slavery to self have been put to death forever.

In Christ, you live.  

You have now been reborn as a beloved son or daughter of God - sharing Jesus' love for God the Father and God the Father's love for Jesus (God the Son).

Your life as God's child will never be extinguished, not even by death.
