Is Baptism a necessary condition for one to be saved? Scripture declares, no! Here are 15 clear passages showing this:
Romans 10:9 (Confess with your mouth, and believe in your heart Jesus is Lord, you will be saved)
1 Cor 1:13-17 (Paul says God did not send him to baptize, but preach the Gospel. This shows the Gospel and Baptism are two different things.)
Eph. 2:8-9; Philipians 3:9; Gal 2:16; Rom 3 (We are saved by faith, as a gift from God, not works)
1 Cor 15:1-4 (A summary of the Gospel, with no attachment to baptism)
Acts 15; Rom 4 (No outward act is necessary for salvation)
Acts 3:12-26 (Peter doesn't mention baptism as a part of his gospel message)
Luke 7:37-50; Matthew 9:2; Luke 18:13-14; Luke 23:43 (People saved apart from baptism)
Acts 10:44-48 (Many people are saved before being baptized)
Baptism is the normal obedience of one who has trusted in Christ. Because Scripture asks us to be baptized, anyone who is a Christ follower will react to their salvation by obeying Scripture's request for a baptism. This outward sign does not create inner transformation, instead it shows inner transformation.
