'Abide in Him' in the Bible

And as for you, the anointing which ye received of him abideth in you, and ye need not that any one teach you; but as his anointing teacheth you; concerning all things, and is true, and is no lie, and even as it taught you, ye abide in him.

And now, my little children, abide in him; that, if he shall be manifested, we may have boldness, and not be ashamed before him at his coming.

But whoso hath the world's goods, and beholdeth his brother in need, and shutteth up his compassion from him, how doth the love of God abide in him?

hereby we know that we abide in him and he in us, because he hath given us of his Spirit.
