Baptism is a way of showing others that you have entered into a personal relationship with Jesus Christ. It symbolizes what took place in your heart at the time of salvation:
Because Jesus instructed us to be baptized, baptism is an act of obedience. While it is not necessary for salvation, it demonstrates submission to God. We immerse because we believe Scripture shows that Jesus modeled that for us as the way to publicly acknowledge our faith in him.
Some denominations choose to christen infants. While we recognize the right of other churches to practice infant christening, we understand Scripture to teach that only professing believers qualify for baptism. Baptism does not make you a believer; rather, it shows that you already believe.
