Yochanan I 2:4

4 The one making the claim, "I have da’as of Him" and not being shomer over His mitzvot is a shakran (liar) and in this one HaEmes is not.

Yochanan I 2:4 Meaning and Commentary

1 John 2:4

He that saith I know him
God or Christ, as the Gnostics did, who pretended to great, even perfect, knowledge of divine things:

and keepeth not his commandments;
which the above persons had no regard to, and as many who profess great light and knowledge in our days show no concern for:

is a liar;
he contradicts what he says, and gives the lie to it; for though in words he professes to know God, in works he denies him, and which betrays his ignorance of him:

and the truth is not in him;
there is no true knowledge of God and Christ in him; nor is the truth of the Gospel in his heart, however it may be in his head; nor is the truth of grace in him, for each of these lead persons to obedience. The Ethiopic version renders it, "the truth of God is not with him"; (See Gill on 1 John 1:8).

Yochanan I 2:4 In-Context

2 And he is the kapporah for chattoteinu, not for ours only, but also for the kol HaOlam Hazeh. [VAYIKRA 5:15; YESHAYAH 53:10]

3 And by this we have da’as that we have da’as of Him, if over the mitzvot of Him we are shomer.

4 The one making the claim, "I have da’as of Him" and not being shomer over His mitzvot is a shakran (liar) and in this one HaEmes is not.

5 But whoever over the dvar of Him is shomer, beemes in this one the ahavas Hashem has been made shleimah. By this we have da’as that in Him we are.

6 The one claiming to make his maon in Him ought with the halakhah of that One so he should have his derech. [Yn 14:1,23; TEHILLIM 1:6]
