Deuteronomy 21:23 You must not leave the body hanging on the pole overnight. Be sure to bury it that same day, because anyone who is hung on a pole is under God’s curse.
We read in this chapter that if anyone in Israel had a rebellious and stubborn son, the son needed to be put to death.
Jesus Christ, the son of God, was cursed by God and put to death (out of His own volition). God gave up His own son as a “rebellious and stubborn” son so that from now on every other rebellious and stubborn son can receive God’s forgiveness.
This is the power of God’s love!
