So look upon your old sin nature as dead and unresponsive to sin, and instead be alive to God, alert to Him through Jesus Christ our Lord. Do not let sin control your puny body any longer; do not give in to its sinful desires (Rom. 6:11,12).
When someone becomes a Christian he becomes a brand new person inside. He is not the same any more. A new life has begun! (2 Cor. 5:17).
