Following Christ:
In order to understand the reason for being water baptized, it is important to carefully consider what the Bible says about it: Jesus himself was baptized. He was not a sinner, yet he humbled himself in obedience to identify with us and give us an example to follow.
See Mark 1:9
An act of obedience:
Water baptism is an act of faith and obedience to the commands of Christ.
See Matthew 28:19-20
A public declaration:
Baptism declares that you are a follower of Jesus Christ. It is a public confession of your faith in, and commitment to, Jesus Christ. It is the next step after salvation through repentance and faith and is an important foundation for Christian life.
See Mark 16:16
