48 Be perfect, therefore, as your heavenly Father is perfect.
48 Be ye therefore perfect, even as your Father which is in heaven is perfect.
48 You therefore must be perfect, as your heavenly Father is perfect.
48 "In a word, what I'm saying is, Grow up. You're kingdom subjects. Now live like it. Live out your God-created identity. Live generously and graciously toward others, the way God lives toward you.
48 Therefore you shall be perfect, just as your Father in heaven is perfect.
48 But you are to be perfect, even as your Father in heaven is perfect.

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.
