Galatians 3:13-14 :
Christ redeemed us from the curse of the law, having become a curse for us. For it is written, “Cursed is everyone who hangs on a tree,” that the blessing of Abraham might come on the Gentiles through Christ Jesus; that we might receive the promise of the Spirit through faith.
God went global with salvation through Grace. Up to the point that Jesus came, God’s plan was only being worked out through the Jews and those who were willing to become Jews. God’s intention was to save the whole world by His act of dying. Paul quotes the Bible where it says that hanging a man on a tree was to be considered a curse. That’s exactly what Jesus allowed to happen to Himself to save us. With the curse of the law paid for, the law was satisfied for all who had ever sinned and would ever sin in the future. Since God recognized the punishment of all of the sins of mankind when Jesus died, non-Jews were included.
The blessing of Abraham, remember, is righteousness that is credited to your account by believing the word of God. It isn’t payment but a credit. Jesus paid, and gave the benefit to us. He is now alive, and because of this so are we, because we were “in” Christ when He died, and are still in Him today as He lives.
Everyone who believes in Jesus receives “the promise of the Spirit through faith.” This is an amazing Gift that was entirely new. Up to that point, the Jews were never given the Spirit to live in them. As we learned earlier, the Spirit and His power are received through believing in God’s word, and that was made possible by Jesus taking the curse. This is why we get to celebrate Thanksgiving, Christmas, and the Resurrection everyday!
