1 John 2:3

1 My little children, these things write I unto you, that ye sin not. And if any man sin, we have an advocate with the Father, Jesus Christ the righteous:

2 And he is the propitiation for our sins: and not for ours only, but also for the sins of the whole world.

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.

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

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