So....just a random crap shoot then? Some get lucky and He lets their offenses slide....others get zapped immediately if God loses His patience for them? (I'm not looking for a response...BTW).
You just quoted an actual Bible text that I had posted, with none of my own words, and disagreed with it.
You are conflating judging of individuals and God working in history. All people are sinners, and all deserve death. Yes, God gives all an opportunity to know Him (see Romans 2), and He also is merciful to those who seek Him. Some do not repent, some have no faith, etc. This is all in regards to individual judgment where faith is the key, as the verses I posted and you agreed with, show. Abraham and David, both heroes of faith, were saved by faith, as sinners.
However, when it comes to God working in history He sometimes chooses to use people despite their problems. A long list has already been provided. That is up to God how He will do these things. The text I referenced is in a section about how God elected the nation of Israel. And that verse was pointing out that it was not based on their superior virtue. God chose Jacob to carry out his will, before he did anything good or bad. That was God's choice about how to use him. And as for Jacob individually he eventually learned faith.
However, God also used other people for His glory that did not learn faith. He used the Assyrian kings to bring about judgment--but they did not combine that with faith. He used Saul to be king, and chose him, but Saul did not combine that with faith.
On the other hand God used Rahab, a prostitute, David, an adulterer and murderer, Sampson a serial womanizer, etc. who did learn faith, despite their sinful nature.
So to say that God could not use Abraham from that perspective does not make sense. All people are sinners, and God uses who He chooses for His ends. Now whether they individually respond to Him in faith and are saved, that is their choice.
All have sinned and fall short of the glory of God. There are no perfect people to use, short of Christ. Yet God uses sinful people to His glory. And in that process they can choose to trust in Him.
