Before the foundation of the world God created and ordained 2 Laws that Paul discusses in Romans 8.
They are the 2 Laws that all Laws stem from, that every creature in the universe must obey, including God Himself.
!) The Law of Sin and Death.
2) The Law of the Spirit of Life in Christ Jesus.
There is no option to these 2 Laws. This is where God demands payment or else!
There are several things from Scripture that help me to see the payment for sin.
Several come from the life of David, here's just one of them.
Remember when the prophet came to David and told him of a man in the kingdom who had just one little lamb.
The man loved and provided for that one lamb, and another man, which had many lambs came and took that one lamb from him.
David flew into a rage and said, As the Lord lives, this man will surly be put to death.
And the prophet said, you are the man! This is referring to David's adultery with Bathsheba.
David's first response, "I have sinned against God." This was David's response many times when he realized he had sinned. The reason God said of him, "the man after my own heart."
He placed God first in his repentance, and sought to make it right with God first.
All the sins David committed in the situation with Uriah and Bathsheba cost him a price. He paid dearly for those mistakes, and God made sure of it, even though he repented in tears and sorrow.
Sin carries a price tag, and the cost is always more than we can afford to pay.
The reason we need to be ransomed, or there is no hope.
