43 You have knowledge that it was said, Have love for your neighbour, and hate for him who is against you: 44 But I say to you, Have love for those who are against you, and make prayer for those who are cruel to you; 45 So that you may be the sons of your Father in heaven; for his sun gives light to the evil and to the good, and he sends rain on the upright man and on the sinner. 46 For if you have love for those who have love for you, what credit is it to you? do not the tax-farmers the same? 47 And if you say, Good day, to your brothers only, what do you do more than others? do not even the Gentiles the same?
Matthew Henry's Commentary on Matthew 5:43-47
Commentary on Matthew 5:43-48
(Read Matthew 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, 1 Peter 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.
