An heir may be either one who is entering on his inheritance or one who is hereafter to enter on it. In a sense, the Christian inheritance is always future; heaven lies ahead. And the NT, with its strong eschatological background, felt the claims of the future more even than we do. Yet preceding verses speak of full sonship in Christ as largely implying entrance on the inheritance. The Spirit is earnest or first-fruits (Romans 8:23; 2 Corinthians 5:5; Ephesians 1:14). Dealing with Israel under the Law, Paul explains that, while an heir, Israel had been a minor, and therefore temporarily no better than a slave. Slave to whom? To the angels or spirits of the elements (mg.; Peake, EGT, on Colossians 2:8, after Spitta). From this bondage Israel was redeemed by the mission of the Son of God born of a woman, i.e. [not necessarily virgin-born but] incarnate as human (cf. Job 14:1), and coming under the Law in order to abolish it and so intro duce the epoch of freedom and sonship (cf. supra on Galatians 3:1-14).

Galatians 4:1-7
1 Now I say, That the heir, as long as he is a child, differeth nothing from a servant, though he be lord of all;
2 But is under tutors and governors until the time appointed of the father.
3 Even so we, when we were children, were in bondage under the elementsa of the world:
4 But when the fulness of the time was come, God sent forth his Son, made of a woman, made under the law,
5 To redeem them that were under the law, that we might receive the adoption of sons.
6 And because ye are sons, God hath sent forth the Spirit of his Son into your hearts, crying, Abba, Father.
7 Wherefore thou art no more a servant, but a son; and if a son, then an heir of God through Christ.
