"They are as close as our skin, the troika of lusts described by the Apostle John: the lust of the flesh, the lust of the eyes, and the boastful pride of life (1 John 2:16). These inordinate and forbidden longings of the sinner are the fountain of sin, as James points out when teaching that God does not tempt us to sin: "But each one is tempted when he is carried away and enticed by his own lust. Then when lust has conceived, it gives birth to sin; and when sin is accomplished, it brings forth death" (James 1:14–15 NASB).
The natural man is in bondage to his lusts (Rom. 3:10–18), but at our conversion, because of our union with Christ, we are delivered from the dominion of lusts: "Therefore do not let sin reign in your mortal body so that you obey its lusts, and do not go on presenting the members of your body to sin as instruments of unrighteousness; but present yourselves to God as those alive from the dead, and your members as instruments of righteousness to God. For sin shall not be master over you, for you are not under law but under grace" (6:12–14)."
