Romans 6:15–23 asks why we should not keep sinning once we have come to faith in Christ and are no longer under the law of Moses. Paul answers that we can continue to lead lives of volunteer slavery to sin if we don’t resist it. Instead, we should live as if righteousness was our master, which, in a sense, it is. We should obey righteousness instead of our sinful desires, in part, because we now understand the consequences of sin. Instead of shame and death, we should serve God who gives eternal life as a gift.
