The New Testament Understanding of Baptism
Therefore, there is a precedent in the Bible (both OT & NT) for a spiritual understanding of circumcision. These passages speak of dedication, repentance, and purity. Col. 2:11–12 fits into this description of circumcision when we examine it closely. The text mentions “putting off the body of the sins of the flesh by the circumcision of Christ” (v. 11). Then comes the connection to baptism. The words of Col. 2:12 echo those in Rom. 6:4.
Christian baptism is an identification with Christ’s death, burial, and resurrection. Rom. 6 is in a context of why believers should not continue in sin though grace abounds (6:1–2). Part of the answer to that question is a discussion on the meaning of baptism. Because we have pledged ourselves to follow Christ and identify with His death, burial, and resurrection, it should make a difference in our lives. Our pledge is not for salvation, but rather it is a commitment made before witnesses (note the examples of many baptisms in the book of Acts) that we intend to live for Him. If we have believingly done that, we should no longer continue in sin. We should forsake it and live in newness of life—a life of dedication.
