That is a question you will have to decide for yourself. But if you choose to be re-baptized, don’t do it based on water baptism saving you. Water baptism is not the baptism that saves. What cleanses us from sin is not the water but the precious blood that Jesus shed on the cross (see Ephesians 1:7; Hebrews 9:22; Revelation 1:5). First John 1:9 says that confession of sin is what puts in motion the power of forgiveness through the blood of Jesus.

The original Greek verb baptidzo means “to immerse.” Immersion is a picture of burial. So, though some churches sprinkle or pour water in the baptismal ceremony, it is when a believer is completely submerged and then raised up out of the water that the complete story is more clearly understood. The old man is dead and buried. A new man is raised up out of the grave, reborn to live a new life by the power of the Holy Spirit. Let your decision be based on your desire to testify through the symbolism of water baptism to what took place in your life when you made Jesus your Lord. Water baptism is an outward sign of the inward grace that takes place in a man’s life at conversion.
