Galatians 3:13

Galatians 3:13. Christ hath redeemed us from the curse of the law, being made a curse for us: for it is written, Cursed is every one that hangeth on a tree:

There is the key of the mystery. Christ is our Substitute. He fulfilled the law’s demands by his perfect obedience, and he suffered the law’s utmost penalty by his death upon the cross; and, now, all those who believe in him are forever justified because of what he did for them.
