“For if ye love them which love you, what thank have ye? for sinners also love those that love them.”
King James Version (KJV)
6:32 It is greatly observable, our Lord has so little regard for one of the highest instances of natural virtue, namely, the returning love for love, that he does not account it even to deserve thanks. For even sinners, saith he, do the same: men who do not regard God at all. Therefore he may do this, who has not taken one step in Christianity.
Lu 6:32 If ye love them which love you, etc. See the note on "Mt 5:44".
