Baptism

If you have accepted Jesus as your Lord and Savior, then the next step for you is baptism. No matter how long ago you made this decision, baptism by IMMERSION is an indispensable step for every Christian.

Therefore go and make disciples of all nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit, 

Matthew 28:19 

Baptism doesn't make you right before God, only faith in Christ does that, but baptism is the outward symbol of the inward transformation Christ has brought about in your life. But it's more than a symbol; it's a step of obedience in your own faith, and you also build the courage and faith of others in the process. It's an act of faith that consists in confessing before God, men, angels and even demons that from now on you belong to God.
