That ye may be the children of your Father - In Greek, the sons of your Father. The word “son” has a variety of significations. See the notes at Matthew 1:1. Christians are called the “sons” or “children” of God in several of these senses: as his offspring; as adopted; as his disciples; as imitators of Him. In this passage the word is applied to them because, in doing good to enemies, they resemble God. He makes His sun to rise upon the evil and good, and sends rain, without distinction, on the just and unjust. So His people should show that they imitate or resemble Him, or that they possess His spirit, by doing good in a similar way.
