J C Ryle's comments on the "Throne of his father David"

In J C Ryle's commentary on Luke's Gospel chapter 1 verses 32 and 33, which reads: He shall be great, and shall be called the Son of the Highest: and the Lord God shall give unto him the throne of his father David: And he shall reign over the house of Jacob for ever; and of his kingdom there shall be no end; he makes the following comments:

Let us beware of spiritualising away the full meaning of these words. The "house of Jacob" does not mean all Christians. The "throne of David" does not mean the office of a Saviour to all Gentile believers. 

The words will yet receive a literal fulfilment, when the Lord Jesus comes the second time, and the Jews are converted. The promise of Gabriel is parallel with Jeremiah 30:9*. The kingdom of which he speaks, is the glorious kingdom foretold in Daniel 7:27**, before which all other kingdoms are finally to be overthrown at Christ's coming. 

*Jeremiah 30:9: But they shall serve the LORD their God, and David their king, whom I will raise up unto them.

**Daniel 7:27: And the kingdom and dominion, and the greatness of the kingdom under the whole heaven, shall be given to the people of the saints of the most High, whose kingdom is an everlasting kingdom, and all dominions shall serve and obey him.
