I have been asked on several occasions what my thoughts are regarding re-baptism.  I have in mind those who were previously baptized in a legitimate Biblical manner, but want to be baptized again for various reasons.  The Bible does not directly address this issue, so we cannot cite chapter and verse to settle it.  We have to think about it theologically and practically.  Here are my thoughts on the matter.

First, we have to consider what makes baptism effective.  According to Paul, it is one’s faith in what God is doing through the act of baptism:

In him also you were circumcised with a circumcision made without hands, by putting off the body of the flesh, by the circumcision of Christ, 12 having been buried with him in baptism, in which you were also raised with him through faith in the powerful working of God, who raised him from the dead. (Col 2:11-12)

If one exercised genuine faith in Jesus when they were baptized, then their baptism was legitimate and spiritually efficacious, and there is no spiritual need to be rebaptized.  They already have the spiritual benefits of baptism applied to their life.  Being rebaptized will add nothing to their spiritual life that they do not possess already.  However, if one did not have faith in Jesus when they were baptized, or if they are not certain whether they had genuine faith at the time and they feel the need to be rebaptized, then by all means they should do so.
