In 1 Corinthians 9:21, Paul writes that he is not “outside the law of God but under the law of Christ” (English Standard Version). Yet elsewhere, he writes, “For sin will not have dominion over you. For you are not under law, but under grace” (Romans 6:14); and, “if you are led by the Spirit, you are not under the law” (Galatians 5:18). Surely, Paul was under grace and led by the Spirit, so why does he describe himself in 1 Corinthians 9:21 as “under the law?” Is it the fact that Paul is speaking of the law of Christ in 1 Corinthians 9:21 that makes the difference? Does grace take us out from under the law of Moses and put us under the law of Christ? Or, does Paul mean something else entirely?
