3 So we, when we were young, were kept under the first rules of the world; 4 But when the time had come, God sent out his Son, made of a woman, made under the law, 5 That he might make them free who were under the law, and that we might be given the place of sons. 6 And because you are sons, God has sent out the Spirit of his Son into our hearts, saying, Abba, Father. 7 So that you are no longer a servant, but a son; and if a son, then the heritage of God is yours.
Matthew Henry's Commentary on Galatians 4:3-7
Commentary on Galatians 4:1-7
(Read Galatians 4:1-7)
The apostle deals plainly with those who urged the law of Moses together with the gospel of Christ, and endeavoured to bring believers under its bondage. They could not fully understand the meaning of the law as given by Moses. And as that was a dispensation of darkness, so of bondage; they were tied to many burdensome rites and observances, by which they were taught and kept subject like a child under tutors and governors. We learn the happier state of Christians under the gospel dispensation. From these verses see the wonders of Divine love and mercy; particularly of God the Father, in sending his Son into the world to redeem and save us; of the Son of God, in submitting so low, and suffering so much for us; and of the Holy Spirit, in condescending to dwell in the hearts of believers, for such gracious purposes. Also, the advantages Christians enjoy under the gospel. Although by nature children of wrath and disobedience, they become by grace children of love, and partake of the nature of the children of God; for he will have all his children resemble him. Among men the eldest son is heir; but all God's children shall have the inheritance of eldest sons. May the temper and conduct of sons ever show our adoption; and may the Holy Spirit witness with our spirits that we are children and heirs of God.
