God’s holiness demands justice because He cannot compromise His perfect righteousness. In other words, because we sinned against a holy God, we deserve the wrath of God. This next part makes no sense--because instead of consuming us, He gave us salvation through Jesus. And that's the undeserving gift of the Gospel of Jesus Christ. "For by grace you have been saved through faith, and that not of yourselves; it is the gift of God, not of works, lest anyone should boast" (Ephesians 2:8-9).
