Truly, the "vital" teacher is God Himself:
AMEN! Great scripture.
***Truly, the “vital” teacher is God Himself:
But the anointing which ye have received of him abideth in you, and ye need not that any man teach you: but as the same anointing teacheth you of all things, and is truth, and is no lie, and even as it hath taught you, ye shall abide in him. - I John 2:27***
God teaches; man does not necessarily have to learn, or else he can learn different things.
All Protestant denominations have learned different things. Are you saying that God has led all the Protestant denominations on their various paths - very often very contradictory?
