Following Christ: 
In order to understand the reason for being water baptised, it is important to carefully consider what the Bible says about it… Jesus himself was baptised. He was not a sinner, yet he humbled himself in obedience to identify with us and give us an example to follow. 
At this time, Jesus came from Nazareth in Galilee and was baptised by John in the Jordan. The moment he came out of the water, he saw the sky split open and God’s Spirit, looking like a dove, come down on him. Along with the Spirit, a voice: “You are my Son, chosen and marked by my love, pride of my life.” 


An Act of Obedience: 
Water baptism is an act of faith and obedience to the commands of Christ. 
“Therefore go and make disciples of all nations, baptising them in the name of the Father and of the Son and of the Holy Spirit, and teaching them to obey everything I have commanded you. And surely I am with you always, to the very end of the age.” 
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 the Christian life. 
Then he said, “Go into the world. Go everywhere and announce the Message of God’s good news to one and all. Whoever believes and is baptized is saved; whoever refuses to believe is damned.” 
Mark 16:16
