1 John 2:7 ASV

⁵  but whoso keepeth his word, in him verily hath the love of God been perfected. Hereby we know that we are in him:

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

⁷  Beloved, no new commandment write I unto you, but an old commandment which ye had from the beginning: the old commandment is the word which ye heard.

⁸  Again, a new commandment write I unto you, which thing is true in him and in you; because the darkness is passing away, and the true light already shineth.

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