1. What is the purpose for the non-elect to repent? What happens if they do? What happens if they don’t.
2. What is the purpose for the elect to repent? Is it strictly a mechanical act? It would seem so.
However, and this is key, the calvinist also believes that REGENERATION PRECEDES individual Faith.
As Jesus said, "Except a man is born again, he canNOT see the kingdom..."
Once the will is renewed through regeneration, THEN he can repent and believe as an act of will.
If you don't get the sequence "regeneration, faith, repentance" correct, then you'll never understand calvinism.
But, I am just a paduwan in the tradition of someone or other. :>)
The non-elect will never repent. God will call and call but they will never come. Noah spent 120 years preaching all the while he was building an ark that would only seat 8 people.
The purpose of the elect to repent is to submit to God. He is holy and He expects it of us. We just don't appreciate HOW holy God really is. We can only come to Him through Christ without being consumed.
