1 John 2:3-6

3 Now by this we know that we know Him, if we keep His commandments.

4 He who says, "I know Him," and does not keep His commandments, is a liar, and the truth is not in him.

5 But whoever keeps His word, truly the love of God is perfected in him. By this we know that we are in Him.

6 He who says he abides in Him ought himself also to walk just as He walked.
