Romans 3:29-30, Only One God
God’s plan to save these scattered descendants of Noah was through a nation. The Jewish people that came through the loins of Abraham. Immediately, in Genesis 12, God called Abraham to fulfil that plan. God gave Israel the law through Moses at Mount Sinai. God’s plan was that Israel will be His witness to bring the nations to the saving knowledge of the One God.
Deuteronomy 4:7-8 For what nation is there so great, who hath God so nigh unto them, as the LORD our God is in all things that we call upon him for? 8 And what nation is there so great, that hath statutes and judgments so righteous as all this law, which I set before you this day?
Indeed, Israel’s role was to reflect God in all manner of their life so as to be a witness to the nations, like a magnet, to bring them back to God. And it is through the Jews that the Saviour of the world, Jesus Christ, would come. The Jews had that pivotal role to present the one God to the nations of the world.
