There is a “growing up maturing” process in which our minds are renewed with the Word of God so we can correctly know and do the perfect Will of God but, it is a process and we need to be taught the Word of God by the Holy Spirit of God.
It’s a waste of time to go around judging and condemning believers. Love and mercy with wisdom is a better choice!
Judging is Gods Job,
I'm not judging anyone, but the doctrine needs to be tested and judged by the word.
Rom 14:13 Let us not therefore judge one another any more: but judge this rather, that no man put a stumblingblock or an occasion to fall in his brother's way.
2Ti 3:16 All scripture is given by inspiration of God, and is profitable for doctrine, for reproof, for correction, for instruction in righteousness:
2Ti 3:17 That the man of God may be perfect, throughly furnished unto all good works.
2Ti 4:2 Preach the word; be instant in season, out of season; reprove, rebuke, exhort with all longsuffering and doctrine.
2Ti 4:3
For the time will come when they will not endure sound doctrine; but after their own lusts shall they heap to themselves teachers, having itching ears;
2Ti 4:4 And they shall turn away their ears from the truth, and shall be turned unto fables.
2Th 2:10 And with all deceivableness of unrighteousness in them that perish; because they received not the love of the truth, that they might be saved.
2Th 2:11 And for this cause God shall send them strong delusion, that they should believe a lie:
2Th 2:12 That they all might be damned who believed not the truth, but had pleasure in unrighteousness.
Not quoting these to condemn or judge anyone. but to show that there are many false doctrines and many that refuse to accept the truth.
