Isaiah 54: God of the World
In most of the Old Testament, it seems as if God is only concerned about the Israelites. In general, it seems as if He is involved with them because they are the chosen people. Of course, there are definite exceptions to this rule such as Melchizedek, but Isaiah 54 points out a major one that would be coming in the future.
Isa 54:2 Enlarge the place of thy tent, and let them stretch forth the curtains of thine habitations: spare not, lengthen thy cords, and strengthen thy stakes;
Isa 54:3 For thou shalt break forth on the right hand and on the left; and thy seed shall inherit the Gentiles, and make the desolate cities to be inhabited.
Isa 54:4 Fear not; for thou shalt not be ashamed: neither be thou confounded; for thou shalt not be put to shame: for thou shalt forget the shame of thy youth, and shalt not remember the reproach of thy widowhood any more.
Isa 54:5 For thy Maker is thine husband; the LORD of hosts is his name; and thy Redeemer the Holy One of Israel; The God of the whole earth shall he be called.
If you recall from yesterday, Isaiah 53 was referring to Jesus coming as the Messiah, and now that we have a tent becoming larger. God had always been the God of the entire earth, but after the Messiah, it would becoming known that He was.
You can see that with the rise of Christianity. Obviously, Judaism was almost exclusively tied to the Jewish people before Christ. Once Christianity begins to have influence, the idea spreads around the world. Even the initial disciples were spreading the Gospel from India to Ethiopia to Rome.
The death of Jesus Christ and the salvation provided through Him was for the entire world, and now we see Christianity as a major world religion.
Again, this must have been a radical prophecy at the time. I am continually struck by the prophecy in the Old Testament. They were earth-changing.
