We all need to read the whole Bible and ask God for understanding. ( myself included) If we choose not to, that is where we err. God is Just and able to forgive, but repentance is still necessary. Jesus answered, “It is not the healthy who need a doctor, but the sick. I have not come to call the righteous, but sinners, to repentance. - Luke 5:31-32
Romans 3 explains just because we are saved by grace, doesn’t give us the right to sin and do wrong. If people don’t “repent” meaning “change turn from their wicked ways,” they will pay the price for it. Bible states if they continue, they will become reprobates unable to distinguish between what is right and what is wrong. Thinking they are wise in their own eyes they become fools, and refuse to return.
