4:3 Even so we, when we were children, were in bondage under the {b} elements of the world:
(b) The Law is called elements, because by the Law God instructed his Church as it were by elements, and afterward poured out his Holy Spirit most plentifully in the time of the Gospel.
4:3 Even so we, when we were children, were in bondage. Both Jews and Gentiles. We were minors, children, not yet delivered from bondage, since the time had not come appointed by the Father.
Under the elements of the world. The law of Moses and whatever law might be diffused among the heathen. The law of Moses was a temporal law, having temporal promises.
4:3 So we - The church of God. When we were children - In our minority, under the legal dispensation. Were in bondage - In a kind of servile state. Under the elements of the world - Under the typical observances of the law, which were like the first elements of grammar, the A B C of children; and were of so gross a nature, as hardly to carry our thoughts beyond this world.
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.
