Baptism is an act of obedience to Christ, and a public confession of faith in Him.
Water baptism symbolizes your participation in Christ's death and resurrection.
“Peter replied, “Repent and be baptized, every one of you, in the name of Jesus Christ for the forgiveness of your sins. And you will receive the gift of the Holy Spirit.”
(Acts 2: 38 NIV)
“And so John the Baptist appeared in the wilderness, preaching a baptism of repentance for the forgiveness of sins. The whole Judean countryside and all the people of Jerusalem went out to him. Confessing their sins, they were baptized by him in the Jordan River.”
(Mark 1: 4, 5 NIV)
“Or don’t you know that all of us who were baptized into Christ Jesus were baptized into his death? We were therefore buried with him through baptism into death in order that, just as Christ was raised from the dead through the glory of the Father, we too may live a new life.”
(Romans 6: 3, 4 NIV)
