1 John 2:5

3 And hereby we do know that we know him, if we keep his commandments.

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

But whoso keepeth his word, in him verily is the love of God perfected: hereby know we that we are in him.

6 He that saith he abideth in him ought himself also so to walk, even as he walked.

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.

Do read the surrounding verses too, because the context often says more than a single verse.
