And thou shalt derive sweet nourishment from the nations, Yea on the bounty of kings shalt thou be sustained,— So shalt thou know— That I、 Yahweh am thy Saviour, and That thy Redeemer is the Mighty One of Jacob.” (Isaiah 60:16, EMPH)

This verse is set in a context in which Isaiah is addressing Israel as a country.  When God sums up and concludes history, the nation of Israel will “derive sweet nourishment from the nations.”  We know, however, that this passage applies beyond just the nation of Israel because vs. 11 [“Your gates shall be open continually; day and night they shall not be shut, that people may bring to you the wealth of the nations, with their kings led in procession.” (Isaiah 60:11, ESV)] is reflected in Rev 21.25, when God sums up all of history and calls home his people to be with him forever.

Isaiah is looking beyond just the Jewish nation to the time when all those who follow Christ by faith will join together for all of eternity to praise and worship God.  We–Christians–will know [by experience] that Yahweh is our Saviour and Redeemer.

This is a promise that cannot cease to amaze us, and if the promise is remarkable, how much greater the actual reality?
