"Turn to me and be saved, all the ends of the earth!” (v22). Through Isaiah, God declared that He was working through King Cyrus and other events for one purpose: “that people may know, from the rising of the sun and from the west, that there is none besides me” (v6). God’s desire was to use Israel to “bless” (Gen 12) the world by sending Jesus, so that the whole earth would be full of His sons and daughters.
“I did not say to the offspring of Jacob, 'Seek me in vain.” (19). Just as God’s work through Israel was not in vain, He works in our lives so that we, and others, will truly know Him.
