1 John 2:3
King James Version
“And hereby we do know that we know him, if we keep his commandments.”
Context
1My 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:
2And he is the propitiation for our sins: and not for ours only, but also for the whole world.
3And hereby we do know that we know him, if we keep his commandments.
4He that saith, I know him, and keepeth not his commandments, is a liar, and the truth is not in him.
5But whoso keepeth his word, in him verily is the love of God perfected: hereby know we that we are in him.
6He that saith he abideth in him ought himself also so to walk, even as he walked.
