1 John 2:4-6
4 He who says, "I know Him," and does not keep His commandments [rather than traditional error], 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.
Beware the Big Lie of Sunday!
