2:26. These things have I written to you concerning them that seduce you.
2:27. And as for you, let the unction, which you have received from him abide in you. And you have no need that any man teach you: but as his unction teacheth you of all things and is truth and is no lie. And as it hath taught you, abide in him.
You have no need, etc... You want not to be taught by any of these men, who, under pretence of imparting more knowledge to you, seek to seduce you (ver. 26), since you are sufficiently taught already, and have all knowledge and grace in the church, with the unction of the Holy Ghost; which these new teachers have no share in.
2:28. And now, little children, abide in him, that when he shall appear we may have confidence and not be confounded by him at his coming.
2:29. If you know that he is just, know ye, that every one also who doth justice is born of him.
1 John Chapter 3
Of the love of God to us. How we may distinguish the children of God and those of the devil. Of loving one another and of purity of conscience.
3:1. Behold what manner of charity the Father hath bestowed upon us, that we should be called and should be the sons of God. Therefore the world knoweth not us, because it knew not him.
3:2. Dearly beloved, we are now the sons of God: and it hath not yet appeared what we shall be. We know that when he shall appear we shall be like to him: because we shall see him as he is.
3:3. And every one that hath this hope in him sanctifieth himself, as he also is holy.
