There is no substitution for the teaching that comes from the Spirit of God. Where did the Apostle Paul get his teaching? What seminary did he attend? How about Peter and John?

1 John 2:27 “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.”
