Words - It all comes down to words
If you write out the statement of belief that we call theologically correct, which defines what as believers would say is sound and excludes various sects and groups who deny the basic faith, how long is it? One page of A4 maybe.
So someone comes and says the words. But the meanings they have gets slightly lost. Is there a gate which now says you have passed over, yep you know enough, you are in and can never leave now, even if you wanted to.
So words have to mean something in the soul of the believer. What we do know is all of us have our own individual version and insight to this. For some it is completely wrong and others completely down the line 100% brilliant.
Now the faith is a commitment to a walk in righteousness not sin. You may have noticed the signs on the way in.
"I repent of my sins" "I ask Jesus to help me walk in righteousness" "I am loved and accepted to be transformed into His likeness"
Now the clue might be righteousness. No evil or imperfect thing in sin will enter the new Kingdom. That is what you have bought into. So the only question is when and how is this transformation going to happen. It is the only argument in town.
Gnostic view - A pure spirit perfect is given to you at the point of faith
Traditional view - We are washed, reborn and as we walk with Jesus transformed through obedience. It gets better with time.
The gnostics say the traditionalists are evil, lost, under judgement, empty. Hyper grace is gnostic. Only those who have been christians many years, know the culture, have been refined over many years suddenly get this revelation, because they already have very few issues in their lives so it is easy to believe such an idea. The evil they create is this condemnation and judgementalism of others, you are evil for doing good but "carnally"
The real problem is they should have had this new spirit already at point of faith, but they never did, so it is just an invention
