5:45 {10} That ye may be the children of your Father which is in heaven: for he maketh his sun to rise on the evil and on the good, and sendeth rain on the just and on the unjust.
(10) A double reason: the one is taken of the relatives, The children must be like their father: the other is taken of comparisons, The children of God must be better than the children of this world.
5:45 That ye may be children of your Father. We are God's children when we have the spirit of our Father. We are not if we have the spirit of the world. Our Father above sends blessing, the rain, and the sunshine, on the just and the unjust. He loves all, and even sent his son to have a wicked world because he loved (Joh 3:16).
5:45 That ye may be the children - That is, that ye may continue and appear such before men and angels. For he maketh his sun to rise - He gives them such blessings as they will receive at his hands. Spiritual blessings they will not receive.
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.
