Therefore put to death your members which are on the earth: fornication, uncleanness, passion, evil desire, and covetousness, which is idolatry. (Colossians 3:5 NKJV)
“Put … to death: The verb is used metaphorically to signify, to deprive a thing of its power, to destroy its strength. Use no member of your body to sin against God; keep all under dominion … To gratify any sensual appetite is to give it the very food and nourishment by which it lives, thrives, and is active. However the body may suffer by excessive sensual indulgences, the appetite increases with the indulgence. Deny yourselves, and let reason rule.”1
