1 John 2:5 WBT

³  And by this we do know that we know him, if we keep his commandments.

⁴  He that saith, I know him, and keepeth not his commandments, is a liar, and the truth is not in him.

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

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

⁷  Brethren, I write no new commandment to you, but an old commandment which ye had from the beginning: The old commandment is the word which ye have heard from the beginning.
