As I said earlier, the Tares of the Church are everywhere. And this, too, is God's will, if you recall Jesus' words on the matter. Very many want to enter the kingdom of God on their terms instead of by the narrow door. But on the last day, Jesus will them that he never knew them!
You really can't accept that it's the "same church" that Paul taught predestination in Christ to is the same church God threatened and commanded to Repent.
You even flat out deny Biblical Truth.
God would not command Repentance and Return to your first works if God did not KNOW YOU.
They were not Tares just backsliders.
