'Abide in Him' in the Bible

But the anointing which ye have received from him abideth in you, and ye need not that any man should teach you: but as the same anointing teacheth you concerning all things, and is truth, and is no lie, and even as it hath taught you, ye shall abide in him.

And now, little children, abide in him; that when he shall appear, we may have confidence, and not be ashamed before him at his coming.
