“Whereas thou hast been forsaken and hated, so that no man went through thee, I will make thee an eternal excellency, a joy of many generations. Thou shalt also suck the milk of the Gentiles, and shalt suck the breast of kings: and thou shalt know that I the LORD am thy Saviour and thy Redeemer, the Mighty One of Jacob.
For brass I will bring gold, and for iron I will bring silver, and for wood brass, and for stones iron: I will also make thy officers peace, and thine exactors righteousness.
Violence shall no more be heard in thy land, wasting nor destruction within thy borders; but thou shalt call thy walls Salvation, and thy gates Praise. The sun shall be no more thy light by day; neither for brightness shall the moon give light unto thee: but the LORD shall be unto thee an everlasting light, and thy God thy glory. Thy sun shall no more go down; neither shall thy moon withdraw itself: for the LORD shall be thine everlasting light, and the days of thy mourning shall be ended.
Thy people also all righteous: they shall inherit the land for ever, the branch of My planting, the work of My hands, that I may be glorified. A little one shall become a thousand, and a small one a strong nation: I the LORD will hasten it in his time.” Isaiah 60:15-22 (KJB)
This is a prophecy, and promise to the people called Israel who was Jacob. It is not a promise to the Church. This will be a result of the work of God’s grace through the Messiah of the Hebrew people, and their realization that He is the Messiah, and He is Jesus Christ.
