A: Baptism is an act of obedience that should be followed by all believers. It is the public demonstration of the fact that it is one's desire to live their life in obedience to Christ.
Romans 6 gives a great explanation of what is intended through Baptism:
Romans 6:3 Or don’t you know that all of us who were baptized into Christ Jesus were baptized into his death? 4 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. 5 If we have been united with him like this in his death, we will certainly also be united with him in his resurrection. 6 For we know that our old self was crucified with him so that the body of sin might be done away with, that we should no longer be slaves to sin—
Q: Does Baptism wash away sin?
A: No, only the blood of Christ can do that.
Q: What are some Bible verses that support baptism?
A: The Book of Acts is the best place to find the Scriptures that describe and give examples of Believer’s Baptism (Acts 8:26-40; Acts 16 gives two great examples).
Q: If I was Baptized before I received Christ, should I be Baptized again?
Q: Does Believers Baptism have any thing to do with Salvation?
A: No, it shows others that you have believed, but plays no part in the salvation decision.
