What does the word 'let' mean in Romans 6:12?
In Romans 6:12, the word 'let' means choice. It is not something forced on the believer but a decision left to their free will. The believer must choose whether to allow old Adam to continue reigning in their mortal body or to keep old Adam in subjection.
Les explains that 'let' in Romans 6:12 implies choice. It is not something forced on the believer, but a decision left to free will. Even as a believer, you must come to a place of decision: will you live a spirit-filled life or a carnal, fleshly life? It is possible for a Christian to make that choice. The admonition is to be led of the Spirit, to live profitable lives, bringing honor and glory to God by keeping old Adam in subjection. God has not taken away the believer's free will. So 'let not' means you choose not to let old Adam continue to reign in your mortal body. Many unhappy believers are miserable because old Adam is still controlling them, but they are the ones left with the choice; he doesn't have to.
Let not sin therefore reign in your mortal body, that ye should obey it in the lusts thereof.
