Isaiah 27:4-6. “Fury is not in Me: who would set the 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. He shall case them that come of Jacob to take root: Israel shall blossom and bud and fill the face of the world with fruit.”
In the Millennium, God is no longer angry with His people because they will be gathered from all nations to make the 12-tribe kingdom of Israel in the Millennium, and they will then be saved and blessed under the Messiah, being no more in rebellion and scattered among the nations (Zech. 14; Acts 15:13-16; Rom. 11:25-29).
God challenges His enemies whom He liken to briers and thorns that would burn by the fury of God in battle. Or, if the enemy does not want to be burned like briers and thorns in the fire, let him take hold of God’s strength and make peace with God, and he will be blessed with Israel.
God will plant Judah and all Israel again like a vineyard being planted, and they will blossom and bud again, and fulfil their calling of filling the whole world with fruit. All nations will be blessed by them (Is. 5:1-7). I did a little research on this blossoming and fruitfulness, and it is already taking place. Israel is producing wonderfully well, and is exporting the fruits of its labors all around the world.
Of course we know that all nations will be blessed by Israel through the person of Jesus Christ, as well.
