Christ redeemed us from the curse of the law by becoming a curse for us — for it is written, “Cursed is everyone who is hanged on a tree.” Galatians 3:13
“To the Jews, this was absolute blasphemy: a cursed Messiah on a cursed cross. No wonder the cross was such a stumbling block to them! To put it in the most shocking and yet perhaps the most accurate way, the apostolic message was about a God-damned Messiah.”
Philip Graham Ryken, Galatians (Phillipsburg, 2005), page 115.
