Jesus is everything that Israel was supposed to be. Israel was supposed to be God’s vine, His vineyard, but they had become a field of wild grapes. Jesus came as the True Vine, and all the branches that abide in Him will bear fruit and be preserved.
“Behold, the Lamb of God who takes away the sin of the world.” Those were the words of John the Baptizer who came as a forerunner of the Messiah. He knew who Jesus was, and he directed others to the savior as well.
