1 John 2:3 - Exposition

And herein we perceive that we know him, if we keep his commandments γινώσκομεν , we come to know, we recognize; ἐγνώκαμεν , we have come to know, we know). The token of our having this knowledge is stated hypothetically; not because, but if, we obey. To serve under another and obey him is one of the best ways of knowing his character. The knowledge is no mere intellectual apprehension, such as the Gnostic, postulated, but a moral and spiritual affection and activity. It is possible to know and hate ( John 16:24 ). Again, the knowledge is not a mere emotional appreciation. Christianity knows nothing of piety without morality. To know Christ is to love him, and to love him is to obey and imitate him. By "keep" τῆρῶμεν is recant "keep the eye fixed upon, observe."
