3 And by this we may be certain that we have knowledge of him, if we keep his laws.
4 The man who says, I have knowledge of him, and does not keep his laws, is false, and there is nothing true in him:
5 But in every man who keeps his word, the love of God is made complete. By this we may be certain that we are in him:
6 He who says that he is living in him, will do as he did.
7 My loved ones, I do not give you a new law, but an old law which you had from the first; this old law is the word which came to your ears.
8 Again, I give you a new law, which is true in him and in you; for the night is near its end and the true light is even now shining out.
9 He who says that he is in the light, and has hate in his heart for his brother, is still in the dark.
