1 John 2

The Children of God
28 And now, little children, abide in Him, that when He appears, we may have confidence and not be ashamed before Him at His coming. 29 If you know that He is righteous, you know that everyone who practices righteousness is born of Him.

1 John 3:1-3

The Command to Love
3 Behold what manner of love the Father has bestowed on us, that we should be called children of God! Therefore the world does not know us, because it did not know Him. 2 Beloved, now we are children of God; and it has not yet been revealed what we shall be, but we know that when He is revealed, we shall be like Him, for we shall see Him as He is. 3 And everyone who has this hope in Him purifies himself, just as He is pure.
