Water baptism is an incredible public start to our faith.  It's the first outward, public action He tells us to do.  Water baptism is symbolic of our old life beging washed away and then we rise to new life.  You can see this in Paul's explanation to the Corinthian church in 2 Corinthians 5:16-17.  Water baptism does bring salvation or gain you points with God, it is simply what saved people do in accordance with Jesus' teachings.  We practice full immersion just like is seen in the Bible.  Please don't over-think this or delay; if you have accepted salvation from Jesus, get signed up for our next time of baptism. Hot Tub
