1 John 2:7

5 But whoso keepeth his word, in him verily is the love of God perfected: hereby know we that we are in him.

6 He that saith he abideth in him ought himself also so to walk, even as he walked.

Brethren, I write no new commandment unto you, but an old commandment which ye had from the beginning. The old commandment is the word which ye have heard from the beginning.

8 Again, a new commandment I write unto you, which thing is true in him and in you: because the darkness is past, and the true light now shineth.

9 He that saith he is in the light, and hateth his brother, is in darkness even until now.

Do read the surrounding verses too, because the context often says more than a single verse.
