FORGIVENESS AND RESTORATION ARE POSSIBLE, even as bad as you’ve been
You’re sins and wickedness can be washed and removed.
God is a god of reason and understanding. He speaks only truth. This makes reasoning together possible. It is impossible to have negotiations with a person who lies or conceals the truth.
God tells us that we can be forgiven. He just told you what you need to do:
This appears to be a reference to the scarlet ribbon that was tied to Azazel (the scapegoat) at Yom Kippur. The ribbon would turn from red to white if the sacrifice was accepted. This would mean that our sins had been covered.
God is telling them that if they repent (demonstrated by honest and sincere actions), then their sins would be wiped away:
Isaiah 43:25
I, even I, am the one who wipes out your transgressions
for My own sake,
And I will not remember your sins.
