That post I replied to is not about repentance or Calvinism.
The point the other poster made was that a person makes themselves into a new creation. But that is false.
God makes His Children into a new creation.
If you want to go back and read the post I replied to, it should be clearer.
The big question I am asking is this: When does the new creation happen? When the person accepts Christ? Or afterwards? And how do we know that it has actually happened?
Does Christ accept the person as soon as the person accepts Christ, and if not, what still needs to happen? The new birth? When does that happen? How do we know? What evidence do we need to see that the person has been truly born again of the Spirit of God?
When they start attending church?
Reading the Bible?
Start using Christian words and expressions?
Wouldn't even hypocrites do those things?
What are the motivations for people wanting to become Christians?
In the 4th century pagans joined the church and become Christians because they had to by Roman Law instituted by the emperor Constantine. Did that make them genuine Christians, born again of the Holy Spirit?
What about those who attend church just for social and cultural reasons, very religious on Sundays, but irreligious every other day of the week? Are they genuine Christians?
What about those who appear in every respect as genuine Christians, but behind the scenes are still practicing homosexuality, fornication, adultery, riotous living, hating people, domestic violence - never seen by others in the church? Have they been born again of the Spirit of God?
Would you say that a person who attends church every Sunday, behaves exactly like a genuine Christian, and yet is senior member of the Masonic Lodge? Has he been born again of the Spirit of God when he is subscribing to the demons who are controlling that Lodge?
