Who should be baptized?
Every person who has made the decision to believe in Christ. When Paul writes to the believers in Rome, he assumes that all of them have been baptized (Romans 6). The one requirement for baptism is belief in Christ!

“Those who accepted his message were baptized….” Acts 2:41

“But when they believed Philip as he preached the good news of the kingdom of God and the name of Jesus Christ, they were baptized, both men and women.” Acts 8:12

We believe in baptizing children when they are old enough to understand what it means and make a personal declaration of belief. (Usually, the age of 12 years old is sometimes a good benchmark.) However I never deny any young person whom has grasped the understanding of being baptized.

When are we to be baptized?
Believers in the New Testament were baptized the same day. As soon as a person decides to believe in Christ, he can be, and is encouraged, to be baptized.
I have often know believers to baptized more than once. Usually after a re-commitment or re-dedication to Christ. I often say sometimes jokingly, be baptized as you felt led or until it takes.

“Those who accepted his message were baptized….” Acts 2:41

“Then Philip began with that very passage of Scripture and told him the good news about Jesus. As they traveled along the road, they came to some water and the eunuch said, “Look, here is water. Why shouldn’t I be baptized?” And he gave orders to stop the chariot. Then both Philip and the eunuch went down into the water and Philip baptized him.” Acts 8:35-39

We pray that these answers will help shed some light on your decision to follow in the footsteps of Jesus.
