Water baptism is one of the ways you first show that you have been joined to Jesus. The symbolism is this: When you go down in the water you show that you have been crucified and buried with Him, and when you come up out of the water you show that you have been raised to walk with Him in newness of life. (See Romans chapter 6)
You have been born again. (See John chapter 3) Your body has become God’s temple. Your heart is where He lives. Forgiveness is yours in Jesus. And you belong to Him. You were sin’s slave. But now…You are a child of GOD!
