43 'Ye heard that it was said: Thou shalt love thy neighbor, and shalt hate thine enemy; 44 but I—I say to you, Love your enemies, bless those cursing you, do good to those hating you, and pray for those accusing you falsely, and persecuting you, 45 that ye may be sons of your Father in the heavens, because His sun He doth cause to rise on evil and good, and He doth send rain on righteous and unrighteous. 46 'For, if ye may love those loving you, what reward have ye? do not also the tax-gatherers 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.
