43 Ye have heard that it has been said, Thou shalt love thy neighbour and hate thine enemy. 44 But I say unto you, Love your enemies, [bless those who curse you,] do good to those who hate you, and pray for those who [insult you and] persecute you, 45 that ye may be [the] sons of your Father who is in [the] heavens; for he makes his sun rise on evil and good, and sends rain on just and unjust. 46 For if ye should love those who love you, what reward have ye? Do not also the tax-gatherers the same? 47 And if ye should salute your brethren only, what do ye extraordinary? Do not also the Gentiles the same?

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.
