Untitled Sermon (3)
The importance of the line of David is highlighted in other OT texts. During the reign of Ahaz, who builds an unauthorized altar in Jerusalem (2 Kgs. 16:10–18), the prophet Isaiah looks forward to the coming of a future, righteous king from the ‘stump of Jesse’ (Is. 11:1–13; cf. 9:1–7; Amos 9:11–15; Mic. 5:2–4). Immediately before and just after the downfall of the house of David at the time of the Babylonian exile, the prophets Jeremiah (Jer. 23:5–6; 33:14–18) and Ezekiel (Ezek. 34:22–24) also anticipate a future Davidic king through whom God will fulfil his purposes for Israel and the nations. Ultimately, as the writers of the NT affirm, this expectation finds its fulfilment in Jesus Christ, ‘the son of David, the son of Abraham’ (Matt. 1:1). With Christ’s death, resurrection and exaltation, God’s promise to bless all the nations of the earth through the seed of Abraham starts to be fully realized (*cf., e.g., Matt. 28:18–20; Gal. 3:14; Rev. 5:9–10).
Abraham’s descendants
God’s promise to Abraham of a future ‘seed’ through whom the nations shall be blessed is closely associated in Genesis with the idea that Abraham’s ‘seed’ will become a great nation (Gen. 12:2). This is necessary in order for a future royal line to be established. Thus, special attention is given to the extent of Abraham’s seed in Genesis 15, where God covenants that they will become numerous and after four centuries take possession of the land of Canaan (Gen. 15:1–21).
Various images, which are not to be taken literally, are used to describe the extent of Abraham’s descendants: they will be as numerous as the stars of heaven (Gen. 15:5; 22:17; 26:4), the dust of the earth (Gen. 13:16; 28:14), and the sand of the seashore (Gen. 22:17; 32:12). These images are repeated later to indicate the fulfilment of the covenant God made with Abraham in Genesis 15. Moses states, ‘The LORD your God has increased your numbers so that today you are as many as the stars in the sky’ (Deut. 1:10; cf. 10:22; 28:62; 1 Chr. 27:23; Neh. 9:23). During the reign of Solomon, the people are as numerous as ‘the sand on the seashore’ (1 Kgs. 4:20) and ‘the dust of the earth’ (2 Chr. 1:9). Moreover, in Solomon’s time the boundaries of the nation are extended to those promised to Abraham (1 Kgs. 4:21; cf. Gen. 15:18–21).
Yet, although Moses anticipated, prior to the Israelite invasion of Canaan, the fulfilment of God’s covenant promise to Abraham, he also looked beyond this to a time when Abraham’s descendants would be ‘but few in number, because you did not obey the LORD your God’ (Deut. 28:62). Furthermore, they will be ‘uprooted from the land’ (Deut. 28:63). Although God fulfils his promise to Abraham that his seed will take possession of Canaan after four hundred years, an important condition for continued occupation of the land is their obedience to God (*cf. Deut. 7:6–11). At the time of the Babylonian exile the prophet Ezekiel condemns the folly of those who lay claim to the land promised to Abraham while living in disobedience to the Lord (Ezek. 33:23–29). Centuries earlier the entire generation of adult Israelites who left Egypt with Moses, apart from Caleb and Joshua, perished in the wilderness without entering Canaan. In the light of this, it is clear that the divine promises to Abraham are only of advantage to those who, like Abraham, trust and obey God. The OT reveals clearly that the biological seed of Abraham must resemble him morally and spiritually in order to be blessed by God. Indeed, implicit in the Hebrew term zera’ is a resemblance between progenitor and progeny (*cf. Gen. 1:11–12).
This idea is picked up in the NT, where first John the Baptist (Matt. 3:9; Luke 3:8) and then Jesus (John 8:31–58) challenge those who see their descent from Abraham as a guarantee of being accepted by God. Indeed, Jesus states that the Pharisees are children of the devil, the hallmarks of their progenitor being their desire to kill him and their rejection of the truth (John 8:44; cf. 1 John 3:8–10). Likewise, Paul emphasizes that the true seed of Abraham are those who through faith in Christ are made right with God: ‘There is neither Jew nor Greek, slave nor free, male nor female, for you are all one in Christ Jesus. If you belong to Christ, then you are Abraham’s seed, and heirs according to the promise’ (Gal. 3:28–29; cf. Rom. 4:13–25).
The NT presents Jesus Christ as the one who brings to fulfilment the divine promises associated with the unique line of seed descended from Abraham. Through Christ God’s blessing is mediated to the nations of the earth. Those who submit in faith and repentance to Jesus Christ as Lord and Saviour resemble Abraham and become his spiritual seed. This seed, produced through the activity of the Holy Spirit, is distinguished by its fruit from the seed which belongs to the evil one.
