11 Beloved, if God so loved us, we also ought to love one another. 12 ^qNo one has ever seen God; if we love one another, God abides in us and ^rhis love is perfected in us.

13 ^sBy this we know that we abide in him and he in us, because he has given us of his Spirit.

20 ^fIf anyone says, “I love God,” and ^ghates his brother, he is a liar; for he who does not love his brother whom he has seen cannot¹ love God ^hwhom he has not seen. 21 And ⁱthis commandment we have from him: ^jwhoever loves God must also love his brother.
