Isaiah 27

Verses 1-13, “In that day the Lord with His severe sword, great and strong, Will punish Leviathan the fleeing serpent, Leviathan that twisted serpent; And He will slay the reptile that is in the sea. In that day sing to her, “A vineyard of red wine! I, the Lord, keep it, I water it every moment; Lest any hurt it, I keep it night and day. Fury is not in Me. Who would set briers and thorns Against Me in battle? I would go through them, I would burn them together. Or let him take hold of My strength, That he may make peace with Me; And he shall make peace with Me.” Those who come He shall cause to take root in Jacob; Israel shall blossom and bud, And fill the face of the world with fruit. Has He struck Israel as He struck those who struck him? Or has He been slain according to the slaughter of those who were slain by Him? In measure, by sending it away, You contended with it. He removes it by His rough wind In the day of the east wind. Therefore by this the iniquity of Jacob will be covered; And this is all the fruit of taking away his sin: When he makes all the stones of the altar Like chalkstones that are beaten to dust, Wooden images and incense altars shall not stand. Yet the fortified city will be  desolate, The habitation forsaken and left like a wilderness; There the calf will feed, and there it will lie down And consume its branches. When its boughs are withered, they will be broken off; The women come and set them on fire. For it is a people of no understanding; Therefore He who made them will not have mercy on them, And He who formed them will show them no favor. And it shall come to pass in that day That the Lord will thresh, From the channel of the River to the Brook of Egypt; And you will be gathered one by one, O you children of Israel. So it shall be in that day: The great trumpet will be blown; They will come, who are about to perish in the land of Assyria, And they who are outcasts in the land of Egypt, And shall worship the Lord in the holy mount at Jerusalem.”

God will have the victory over Leviathan, also known as the serpent of the sea. Satan is identified as having manifest himself as a serpent in the garden, and responsible for tempting Eve and introducing sin and death to the human race. In the final battle, when sin and death are conquered, Jesus will destroy a reptile like beast of the sea who was given power from Satan. Revelation 13:1‭-‬4, “Then I stood on the sand of the sea. And I saw a beast rising up out of the sea, having seven heads and ten horns, and on his horns ten crowns, and on his heads a blasphemous name. Now the beast which I saw was like a leopard, his feet were like the feet of a bear, and his mouth like the mouth of a lion. The dragon gave him his power, his throne, and great authority. And I saw one of his heads as if it had been mortally wounded, and his deadly wound was healed. And all the world marveled and followed the beast. So they worshiped the dragon who gave authority to the beast; and they worshiped the beast, saying, 'Who is like the beast? Who is able to make war with him?' ”

During the reign of Jesus Christ, He will keep His vineyard, watering and protecting it. No enemy will be strong enough to take Him on, and therefore all will make peace with Him and His vineyard. Those who come will be rooted in Him, and fill the whole earth with fruit. The only way we can produce fruit is if we indeed abide in the vine.  John 15:4‭-‬8, “Abide in Me, and I in you. As the branch cannot bear fruit of itself, unless it abides in the vine, neither can you, unless you abide in Me. “I am the vine, you are the branches. He who abides in Me, and I in him, bears much fruit; for without Me you can do nothing. If anyone does not abide in Me, he is cast out as a branch and is withered; and they gather them and throw them into the fire, and they are burned. If you abide in Me, and My words abide in you, you will ask what you desire, and it shall be done for you.  By this My Father is glorified, that you bear much fruit; so you will be My disciples.”

The mistake that some Christians make is that they think they (the church) have replaced Israel. Another fallacy is that they believe they are eternally secure, even if they aren't bearing good fruit. Remember that God's covenant with these people is irrevocable. Although their rejection of their Messiah has allowed for the gentiles to be grafted into the vine, God will graft them in once again. And when the gentiles cease to bear fruit, they will be cut off for their rejection, just like the Jews were...except that we were not given the same promise.  Romans 11:17‭-‬22, “And if some of the branches were broken off, and you, being a wild olive tree, were grafted in among them, and with them became a partaker of the root and fatness of the olive tree, do not boast against the branches. But if you do boast, remember that you do not support the root, but the root supports you. You will say then, “Branches were broken off that I might be grafted in.” Well said. Because of unbelief they were broken off, and you stand by faith. Do not be haughty, but fear. For if God did not spare the natural branches, He may not spare you either. Therefore consider the goodness and severity of God: on those who fell, severity; but toward you, goodness, if you continue in His goodness. Otherwise you also will be cut off.”
