The devil hates the law cuz when people look at God's law they become aware of their sin and recognize they're need for a savior. if devil can get rid of the law he can hypnotize people into thinking that everything is alright when in reality it isn't. As the great "I AM," He Himself proclaimed the Father's moral law from Sinai (John 8:58; Ex. 3:14). Part of His mission on earth was to "magnify the law and make it honorable" (Isa. 42:21). Psalm 89:34 “My covenant will I not break, nor alter the thing that is gone out of My lips” John 15:10 “I have kept my Father's commandments”
