1 Juan 2:4

4 El que dice, Yo le he conocido, y no guarda sus mandamientos, el tal es mentiroso, y no hay verdad en él;

1 Juan 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).

1 Juan 2:4 In-Context

2 Y él es la propiciación por nuestros pecados: y no solamente por los nuestros, sino también por los de todo el mundo.

3 Y en esto sabemos que nosotros le hemos conocido, si guardamos sus mandamientos.

4 El que dice, Yo le he conocido, y no guarda sus mandamientos, el tal es mentiroso, y no hay verdad en él;

5 Mas el que guarda su palabra, la caridad de Dios está verdaderamente perfecta en él: por esto sabemos que estamos en él.

6 El que dice que está en él, debe andar como él anduvo.
