1 John 2:3-5

Noyes(i) 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 whoever keepeth his word, truly in him is the love of God perfected. Hereby we know that we are in him.
