Furthermore, just as they did not think it worthwhile to retain the knowledge of God, so God gave them over to a depraved mind, so that they do what ought not to be done. They have become filled with every kind of wickedness, evil, greed and depravity. They are full of envy, murder, strife, deceit and malice. They are gossips, slanderers, God-haters, insolent, arrogant and boastful; they invent ways of doing evil; they disobey their parents; they have no understanding, no fidelity, no love, no mercy. Romans 1:28-31
In this third “God gave them over to” phrase, we see a long list of vices that God allowed people to commit after they rejected God. Obviously there are many more sins in the world than this, but this gives us a broad idea.
There seems to be a line between God wanting people to come to salvation and God just letting people do their own thing. I’m not sure where that line is or when it is crossed. I do know this that the further someone steps away from God (applies to Christians and non-Christians alike), the more difficult it is for that person to repent. Keeping short accounts with God is always a good practice.
But the unbelievably good news is that even if we’ve blown it ten thousand times (before or after becoming a Christian), God is patient and wants us to repent. He wants us to call Him.
