And now the Lord says, Who formed Me from the womb to be His Servant, to bring Jacob back to Him, So that Israel is gathered to Him. – Isaiah 49:5
Another purpose of our Lord Jesus Christ was to restore Israel back to God.
The people of Israel have always occupied a special place in the heart of God. Even after numerous sins and retributions, as recorded in the Bible, they remain very dear to God. Having called them out of other nations through Abraham, their ancestor, whom He promised a son to who would, in turn, be progenitor to these special people, He has kept faith with them through the ages – establishing and renewing His covenants with them, sustaining and protecting them, answering them whenever they called as well as starting the Agenda of Salvation with them; “for salvation is of the Jews” (John 4:22).
Despite the many overtures of God, the Israelites were notorious for running afoul of His precepts. The Bible is replete with instances of their up-and-down relationship with God, with various degrees of chastisement that usually followed their violation – the height of which was banishment from the land promised to them and their having to serve as slaves in foreign lands.
Yet, God still orchestrated their return back to the Promised Land and was with them in the process of rebuilding that ensued after that. Nonetheless, their relationship with God was characteristically feisty such that He had to embrace non-Jews, otherwise called the Gentiles, in a covenanted relationship, with all the perks that were originally meant for the Jews thrown into the equation (read Romans 11).
However, God has not given up on His chosen people, Israel, and restoring them to Himself was one of the reasons He sent His beloved Son to the earth (Romans 10). Indeed, God does not give up on anyone; but desires that all may come to Him for own good.
