and I didn't make up God's Laws. This is the New Testament (or New Covenant), a covenant of Grace. What you see as atrocities in the Old Testament is life under a covenant of Law. In that world people had to keep God's Laws or pay the price. The Old Testament reveals sin and God's attitude toward it. It's patently obvious from Old Testament examples that no fallen human can keep God's Laws.
1 Corinthians 10:6-11 tells us why the Old Testament was given to us:
"Now these things happened as examples for us, so that we would not crave evil things as they also craved. Do not be idolaters, as some of them were; as it is written, “The people sat down to eat and drink, and stood up to play.” Nor let us act immorally, as some of them did, and twenty-three thousand fell in one day. Nor let us try the Lord, as some of them did, and were destroyed by the serpents. Nor grumble, as some of them did, and were destroyed by the destroyer. Now these things happened to them as an example, and they were written for our instruction, upon whom the ends of the ages have come."
Jesus brought us a way to peace with God wherein we can be justified through faith in Him because He was able to keep the Law perfectly.
"For by grace you have been saved through faith. And this is not your own doing; it is the gift of God, not a result of works, so that no one may boast. For we are his workmanship, created in Christ Jesus for good works, which God prepared beforehand, that we should walk in them." Ephesians 2:8-11
