1 John 2:4

4 He that saith, I know him, and keepeth not his commandments, is a liar, and the truth is not in him.

1 John 2:7-8

7 Brethren, I write no new commandment unto you, but an old commandment which ye had from the beginning. The old commandment is the word which ye have heard from the beginning.

8 Again, a new commandment I write unto you, which thing is true in him and in you: because the darkness is past, and the true light now shineth.

1 John 3:22-24

22 And whatsoever we ask, we receive of him, because we keep his commandments, and do those things that are pleasing in his sight.

23 And this is his commandment, That we should believe on the name of his Son Jesus Christ, and love one another, as he gave us commandment.

24 And he that keepeth his commandments dwelleth in him, and he in him. And hereby we know that he abideth in us, by the Spirit which he hath given us.

1 John 4:21

21 And this commandment have we from him, That he who loveth God love his brother also.

1 John 5:3

3 For this is the love of God, that we keep his commandments: and his commandments are not grievous.
