INTRODUCTION TO ISAIAH 40 This chapter treats of the comforts of God's people; of the forerunner and coming of the Messiah; of his work, and the dignity of his person; of the folly of making idols, and of the groundless complaints of the church of God. The consolations of God's people, by whom to be administered, and the matter, ground, and reason of them, Isa 40:1. John the Baptist, the harbinger of Christ, is described by his work and office, and the effects of it; it issuing in the humiliation of some, and the exaltation of others, and in the revelation of the glory of Christ, Isa 40:3, then follows an order to every minister of the Gospel what he should preach and publish; the weakness and insufficiency of men to anything that is spiritually good; their fading and withering goodliness, which is to be ascribed to the blowing of the Spirit of God upon it; and the firmness and constancy of the word of God is declared, Isa 40:6, next the apostles of Christ in Jerusalem are particularly exhorted to publish fervently and openly the good tidings of the Gospel; to proclaim the coming of Christ, the manner of it, and the work he came about; and to signify his faithful discharge of his office as a shepherd, Isa 40:9, the dignity of whose person is set forth by his almighty power, by his infinite wisdom, and by the greatness of his majesty, in comparison of which all nations and things are as nothing, Isa 40:12 and then the vanity of framing any likeness to God, and of forming idols for worship, is observed, Isa 40:18, and from the consideration of the divine power in creation and upholding all things, the church of God is encouraged to expect renewed strength and persevering grace, and is blamed for giving way to a distrustful and murmuring spirit, Isa 40:26.
