Matthew 5:45

“That ye may be the children of your father, etc.] Not that any became the children of God, by doing things in imitation of him: for as in nature no man becomes the son of another by imitating him, or by doing the things he does but either by birth, or by adoption; so in grace no man becomes a child of God by the works he does, as a follower of God, but by adopting grace; and which is discovered in regeneration. Christ’s meaning is, that they might appear, and be known to be the children of God, by doing those things in which they resemble their heavenly Father; and which are agreeable to his nature and conduct; as the tree is known by its fruit, and the cause by its effect: for where…”

“That ye may be the children--sons. of your Father which is in heaven--The meaning is, "that ye may show yourselves to be such by resembling Him" (compare Mat 5:9; Eph 5:1). for he maketh his sun--"your Father's sun." Well might BENGEL exclaim, "Magnificent appellation!" to rise on the evil and on the good, and sendeth rain on the just and on the unjust--rather, (without the article) "on evil and good, and on just and unjust."

“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. return to 'Top of Page'”

“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. Matthew 5:46”

“5:45 By loving all people, Jesus’ followers would not become children of God; they would show by their actions that they are indeed God’s true children, according to his nature and will (see Deut 10:18-19).”
