Water baptism is obedience to the command of Jesus. He Himself was baptized, setting an example for us to follow.
It was Jesus’ last instruction to his disciples. Last instructions are often the most important words one wants to communicate.
Matthew 28:18-20, Mark 16:15-16
Water baptism is an outward sign of an inward work in your life. When you go into the water you show other people that you are following Jesus with your life.
Water Baptism is a picture of what Jesus did in His death, burial, and resurrection.
1 Peter 3:21
