All Flesh Shall Worship the Lord
The prophet makes it clear that, whatever blessings accrue in the golden future, they will be apportioned to those alone, who are the Israel of God, not merely by descent but in heart and life. They must be what the Apostle describes in Philippians 3:3. Those who were bent on practicing idolatrous rites, such as passing in procession, with priests as teachers, through gardens and groves devoted to impurity; or who, by partaking of the flesh of animals forbidden in the Levitical law, had become as Gentiles, must suffer with the heathen.
Isaiah 66:19 suggests that the restored Jewish remnant are to become the future missionaries of the world; and the book closes with a vision of the Holy City as the focus and center of the religious life of mankind. It is as though, like John, Isaiah beheld her descending from God out of heaven, with wide-open gates, through which the kings of the earth bring their glory and honor, Isaiah 66:20. The lot of all enemies of goodness is depicted in the everburning fires of Tophet-the rubbish heaps of which are significant of uselessness, Isaiah 66:24.
