Essentially you are saying you wish to disregard the OT entirely because it contains too many bad stories about your God. So, I guess you don't believe in Adam and & Eve and the Great Flood. That pretty much leaves nature and evolution.
Please quote one thing Jesus said and then provide evidence for your claim.
In the beginning, God’s plan
“Therefore a man shall leave his father and mother and be joined to his wife, and they shall become one flesh.”
Genesis 2:24 NKJV
After man rebelled and sinned, they brought death, curse, war, which is what you’re referencing in your verses is the result of man’s evil heart apart from God.
Then Jesus comes and says the same thing among other things which are too many to post but you can read yourself:
“The Pharisees also came to Him, testing Him, and saying to Him, “Is it lawful for a man to divorce his wife for just any reason?” And He answered and said to them, “Have you not read that He who made them at the beginning ‘made them male and female,’ and said, ‘For this reason a man shall leave his father and mother and be joined to his wife, and the two shall become one flesh’? So then, they are no longer two but one flesh. Therefore what God has joined together, let not man separate.” They said to Him, “Why then did Moses command to give a certificate of divorce, and to put her away?” He said to them, “Moses, because of the hardness of your hearts, permitted you to divorce your wives, but from the beginning it was not so.”
Matthew 19:3-8 NKJV
