I John 2:3-6
I John 2:3-6 NKJV
Now by this we know that we know Him, if we keep His commandments. He who says, “I know Him,” and does not keep His commandments, is a liar, and the truth is not in him. But whoever keeps His word, truly the love of God is perfected in him. By this we know that we are in Him. He who says he abides in Him ought himself also to walk just as He walked.
