Baptism is an important step in your spiritual journey of faith in Christ. Baptism does not make you a believer. But it is an obedient response and expression of your faith and commitment to Christ. Every example we see in the Bible demonstrates that first a person comes to believe in Christ, and then he or she is baptized as an expression of that belief. Baptism is the means by which followers of Christ are identified. In Matthew 28:19 Jesus commands his followers, 

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