Undefeated
You seem confused. Just because there were good rules for God's ancient people that may no longer apply the same now does not mean we divorce ourselves from it. No more than we divorce ourselves from the garden of Eden. No more than we divorce ourselves from heaven.You obviously do not know your Christian History. If the early Christians really wanted to divorce themselves from the Old Testament, they would have followed Marcion instead of hereticizing him. You do know who Marcion is, don't you?
However, since they did not follow Marcion, you are left with the Gospels and Jesus' words.
“Do not think that I have come to abolish the law or the prophets. I have come not to abolish but to fulfill. Amen, I say to you, until heaven and earth pass away, not the smallest part or the smallest part of a letter will pass from the law, until all things have taken place.” (Matthew 5:17)
“Did not Moses give you the law, and yet none of you keepeth the law” (John7:19)
You don't get to decide. Jesus did that for you.
The Gospels were written after the Flud. Don't you know that? I'll remind you, again, of what Jesus said...
“Do not think that I have come to abolish the law or the prophets. I have come not to abolish but to fulfill. (Matthew 5:17)
We take lessons from the past, they were written for our benefit.
