Charles Ellicott Commentary Revelation 15:7

"And one of the four living creatures gave unto the seven angels seven golden bowls full of the wrath of God, who liveth for ever and ever." — Revelation 15:7 (ASV)

And one of the four . . . More accurately, And one from among the four living beings gave to the seven angels seven golden vials (or, bowls) full, and so forth. The vials are the shallow bowls which were used for incense. They are filled with the wrath of God, and that wrath is now to be poured out upon the kingdoms that have not called upon God’s name (Psalms 79:6).

These vials are given by one of the living creatures who represent creation. It is thus through creation that the wrath of God can visit the rebellious. That wrath of God is simply the operation of God’s righteous law against sin. His statutes are eternally righteous. He has given to all things a law which cannot be broken. That law is adverse to evil and will, in the end, root it out, for it does the bidding of God, who lives forever and ever.
