5:43-48 The Jewish teachers by neighbour understood only those who were of their own country, nation, and religion, whom they were pleased to look upon as their friends. The Lord Jesus teaches that we must do all the real kindness we can to all, especially to their souls. We must pray for them. While many will render good for good, we must render good for evil; and this will speak a nobler principle than most men act by. Others salute their brethren, and embrace those of their own party, and way, and opinion, but we must not so confine our respect. It is the duty of Christians to desire, and aim at, and press towards perfection in grace and holiness. And therein we must study to conform ourselves to the example of our heavenly Father, 1Pe 1:15,16. Surely more is to be expected from the followers of Christ than from others; surely more will be found in them than in others. Let us beg of God to enable us to prove ourselves his children.
46. For if ye love them which love you, what reward have ye? do not even the publicans the same?—The publicans, as collectors of taxes due to the Roman government, were ever on this account obnoxious to the Jews, who sat uneasy under a foreign yoke, and disliked whatever brought this unpleasantly before them. But the extortion practiced by this class made them hateful to the community, who in their current speech ranked them with "harlots." Nor does our Lord scruple to speak of them as others did, which we may be sure He never would have done if it had been calumnious. The meaning, then, is, "In loving those who love you, there is no evidence of superior principle; the worst of men will do this: even a publican will go that length."
