There is nothing deceitful in God's message. He gives men an honest choice, obey or death. Trouble is men always choose death. If you break one commandment you break them all. But no matter how many times God resets the clock to give us "another chance", we will still break His commandments. You're focus solely upon Eze 18 whereas you need to focus on Eze 36:26. Ezekiel 18 is the law. Ezekiel 36 is grace.
And Paul understood the difference.
Drama, drama, drama.
Eze 36 is about the Jews. Do not think it concerns you.
"Then will you dwell in the land that I gave your fathers, and you will be a people to Me, and I will be to you as a God" [Tanach, Yechezkiel 36:24, 28]
