Co-Crucifixion. Have you made the following decision about sin—that it must be completely killed in you? It takes a long time to come to the point of making this complete and effective decision about sin. It is, however, the greatest moment in your life once you decide that sin must die in you-not simply be restrained, suppressed, or counteracted, but crucified—just as Jesus Christ died for the sin of the world. No one can bring anyone else to this decision. We may be mentally and spiritually convinced, but what we need to do is actually make the decision that Paul urged us to do in this passage.
