1 John 2:3-6

3 And hereby we 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 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 that he abideth in Him, ought himself also so to walk, even as He walked.
