What does Isaiah 27:6 mean?
The song of the vineyard continues (Isaiah 27:2–5). The Lord sings from the perspective of the future reality of His reign as king on earth, when all will be made right, as well as from the viewpoint of Isaiah's era.It's made even clearer that this song refers to His chosen people. Jacob was the father of the nation, and God had renamed Him Israel (Genesis 32:28). Jacob's name is often used in place of the word "Israel." In the end times, Jacob / Israel will grow like a vine in a well-tended vineyard. Israel will blossom, and the world will be filled with the fruit of her vine. In the language of the song, this will become possible because the Lord will protect Israel from her enemies and create the perfect conditions for the vine to grow and thrive.
In terms of the future, the greatest fruit of Israel will be the Messiah, Jesus Christ, the Lord Himself (Isaiah 11:1; Jeremiah 33:14). Through faith in the Messiah, believers from the entire world will come into relationship with the God of Israel. They will receive His protection and provision. As He promised Abraham, "In you [through your descendants] all the families of the earth shall be blessed" (Genesis 12:3).
