Satan’s lie: “You’re being so legalistic! The law is dead and only brings death.”
The truth: God still has standards of behavior for us, and you’re responsible to live purely by His standards.
It is God’s will that you should be sanctified: that you should avoid sexual immorality; that each of you should learn to control his own body in a way that is holy and honorable, not in passionate lust like the heathen, who do not know God… For God did not call us to be impure, but to live a holy life. (I THESSALONIANS 4:3-5:7. emphasis added)
