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

And by this we may be certain that we have knowledge of him, if we keep his laws.

Και εν τουτω γνωριζομεν οτι εγνωρισαμεν αυτον, εαν τας εντολας αυτου φυλαττωμεν.

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