14 And you will see it and your heart will be glad, and your bones will get new strength, like young grass: and the hand of the Lord will be seen at work for his servants, and his wrath against his haters.

15 For the Lord is coming with fire, and his war-carriages will be like the storm-wind; to give punishment in the heat of his wrath, and his passion is like flames of fire. 16 For with fire and sword will the Lord come, judging all the earth, and his sword will be on all flesh: and great numbers will be put to death by him.

Matthew Henry's Commentary on Isaiah 66:14-16

Commentary on Isaiah 66:5-14

(Read Isaiah 66:5-14)

The prophet turns to those that trembled at God's word, to comfort and encourage them. The Lord will appear, to the joy of the humble believer, and to the confusion of hypocrites and persecutors. When the Spirit was poured out, and the gospel went forth from Zion, multitudes were converted in a little time. The word of God, especially his promises, and ordinances, are the consolations of the church. The true happiness of all Christians is increased by every convert brought to Christ. The gospel brings with it, wherever it is received in its power, such a river of peace, as will carry us to the ocean of boundless and endless bliss. Divine comforts reach the inward man; the joy of the Lord will be the strength of the believer. Both God's mercy and justice shall be manifested, and for ever magnified.

Commentary on Isaiah 66:15-24

(Read Isaiah 66:15-24)

A prophetic declaration is given of the Lord's vengeance on all enemies of his church, especially that of all antichristian opposers of the gospel in the latter days. Verses 19,20, set forth the abundance of means for conversion of sinners. These expressions are figurative, and express the plentiful and gracious helps for bringing God's elect home to Christ. All shall be welcome; and nothing shall be wanting for their assistance and encouragement. A gospel ministry shall be set up in the church; they would have solemn worship before the Lord. In the last verse the nature of the punishment of sinners in the world to come is represented. Then shall the righteous and wicked be separated. Our Saviour applies this to the everlasting misery and torment of impenitent sinners in the future state. To the honour of that free grace which thus distinguishes them, let the redeemed of the Lord, with humility, and not without holy trembling, sing triumphant songs. With this affecting representation of the opposite states of the righteous and wicked, characters which include the whole human race, Isaiah concludes his prophecies. May God grant, for Christ's sake, that our portion may be with those who fear and love his name, who cleave to his truths, and persevere in every good work, looking to receive from the Lord Jesus Christ the gracious invitation, Come, ye blessed of my Father, inherit the kingdom prepared for you from the foundation of the world.
