1 John 2:2-6

2And He Himself is the propitiation for our sins, and not for ours only but also for the whole world.

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

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

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

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