I wish I had the time to give you the answers you seek.
God always keeps his promises.
When God created man in his own image and placed him in the perfect garden and gave man commandments to follow, man failed to make the right choice. As a result sin set in and the curse of death had to be fulfilled.
In order to overcome the curse of death it took a perfect man in the form of Jesus to be sacrificed for the sins of all the world, God sacrificed himself for our sin debt, so that we might live. He sacrificed himself for man to be able to live with Him, otherwise we would all be damned to hell. Hell is a place apart from God and was originally reserved for the fallen angels. When man fell into sin we had the same cures of death and to be permanently separated from God.
Only God himself was able to provide the way and His plan was through Jesus.
Sorry I have to work, and I don’t have time to pull scriptures to help you understand.
