1 Juan 4:21

21 Y él nos ha dado el siguiente mandato: los que aman a Dios amen también a sus hermanos en Cristo.

1 Juan 4:21 Meaning and Commentary

1 John 4:21

And this commandment have we from him
Either "from God", as the Alexandrian copy and the Vulgate Latin version read; and that to love the brethren is a commandment of God, is clear from ( 1 John 3:23 ) ; or from Christ, for it is also a command of his, even his new commandment, which he has given, and his people have received from him:

that he who loveth God, love his brother also;
see ( John 13:34 ) ( John 15:12 John 15:17 ) ; which is an argument persuading to attend to the one as well as to the other; for the same command that requires the one, requires the other: and he that transgresses it in one case, is a transgressor of it, as well as in the other.

1 Juan 4:21 In-Context

19 Nos amamos unos a otros,
porque él nos amó primero.

20 Si alguien dice: «Amo a Dios» pero odia a un hermano en Cristo, esa persona es mentirosa pues, si no amamos a quienes podemos ver, ¿cómo vamos a amar a Dios, a quien no podemos ver?

21 Y él nos ha dado el siguiente mandato: los que aman a Dios amen también a sus hermanos en Cristo.
