Isaiah 6:3
And one cried unto another, and said, Holy, holy, holy, is the LORD of hosts: the whole earth is full of his glory.
And one cried unto another,.... This denotes the publicness of their ministry, and their harmony and unity in it; they answered to one another, and agreed in what they said; their preaching was not yea and nay, 2 Corinthians 1:19:
and said, Holy, holy, holy is the Lord of hosts; this expresses the subject matter of the Gospel ministry, respecting the holiness of God; all the doctrines of the Gospel are pure and holy, and have a tendency to promote holiness of heart and life, and are agreeable to the holiness of God, and in them the holiness of God in each of the divine Persons is declared; particularly the Gospel ministry affirms that there is one God, who is the Lord of hosts, of armies above and below, of angels and men; that there are three Persons in the Godhead, Father, Son, and Spirit; and that each of these three are glorious in holiness; there is the Holy Father, and the Holy Son, and the Holy Ghost, and the holiness of them is displayed in each of the doctrines of grace: the holiness of the Father appears in the choice of persons to eternal life, through sanctification of the Spirit; in the covenant of grace, which provides for the holiness of covenant ones; and in the justification of his people through Christ, and redemption by him, whereby the honour of his justice and holiness is secured: the holiness of the Son appears in his incarnation and life; in redemption from sin by him, and in satisfying for it, and justifying from it: and the holiness of the Spirit is seen in the doctrines of regeneration and sanctification, ascribed unto him.
the whole earth is full of his glory; as it was when Christ dwelt in it, wrought his miracles, and manifested forth his glory, and when his Gospel was preached everywhere by his apostles; and as it will be, more especially in the latter day, when it will be filled with the knowledge of the Lord; when the kingdoms of this world will become his, and his kingdom will be everywhere, even from sea to sea, and from the rivers to the ends of the earth; and this is what Gospel ministers declare will be: or "the fulness of the whole earth is his glory" {m}; the earth is his, and all that is in it, and all declare his glory; see Revelation 4:8.
