Galatians 3:13a,29 ... Christ has redeemed us from the curse of the law, having become a curse for us ... and if you are Christ's, then you are Abraham's seed, and heirs according to the Promise.
The curse of the law is still out there ... the devil has ownership of it, and he's trying his best to put it on people. so if he's trying to put it on you ... is he telling "the Truth"? You can believe a lie as if it was the Truth ... it doesn't make it any less real. Realness of a thing does not make it the Truth though. The real Truth is found only in God's Word.
Talk to someone who has cancer in his/her body ... that cancer is real. It's a fleshly thing. Doctors can see it, analyze it, and check it out. It's real ... but it's part of the curse.
As born-again Christians, we have been redeemed from the curse of the law (Deuteronomy 28:15-68). Jesus bore all this on His own body when He was crucified so we wouldn't have to bear it in our bodies.
The devil uses the law to kill, steal, and destroy. John 10:10 tells us that he's the thief, and he comes to kill, steal, and destroy.
