Romans 8:3-4
3 For what the law could not do in that it was weak through the flesh, God did by sending His own Son in the likeness of sinful flesh, on account of sin: He condemned sin in the flesh, 4 that the righteous requirement of the law might be fulfilled in us who do not walk according to the flesh but according to the Spirit.

The law of fulfillment of requirements, of works we must do to earn God’s favor to be saved from sin and enter into heaven, that Law was too weak to save any - and that is what was brought back to mind before a corrupt church of such works 500 years ago today. Instead of letting us continue with religious attempts to work harder to no avail, God sent His Son in our sinful flesh to condemn the sin and pay our price. So the law’s demand of payment (death earned) was paid by the very God we offended, fulfilling that requirement over us forever. Jesus paid he price to justify us solely by His righteousness. Now we live in His Spirit, not our old man of sinful flesh. We truly are justified by Christ, faith, grace, Scriptures, and for God’s glory alone.
