The seventh plague poured out upon the air or spirit of this world accomplishes these things and also much more, because it affects the atmosphere itself. Therefore Revelation 16:21 continues: “And a great hail with every stone about the weight of a talent descended out of heaven upon the men, and the men blasphemed God due to the plague of hail, because the plague of it was unusually great.” So from the atmosphere there crash down hailstones on men, hailstones of tremendous size, weighing ninety-six pounds avoirdupois. They fall with great speed and cause stupendous destruction. Since hailstones are congealed water, this hailstorm pictures that heaven would send down upon worldly mankind a barrage of hard Biblical truths. Jehovah’s witnesses are now preaching a message of deliverance and salvation for those who will take refuge in the Kingdom, which cannot be shaken. But the hailstones picture, not a message of deliverance, but the hard, unyielding proclamation of God’s vengeance against Satan’s visible organization. Jehovah’s witnesses will at the last deliver this stinging message, presaging the destruction of the men upon whom it falls.
The men who are affected by this hailstorm are those who did not call upon the name of Jehovah for salvation, but who blasphemed him at hearing the judgment messages and the execution of these. They refused in the past to hear the message that would have meant salvation for them and now they especially hate this condemning declaration. (Joel 2:32; Rom. 10:13) The fact that the plague of it was unusually great foreshows that at the last there will be an unusually great proclamation of God’s vengeance by Jehovah’s witnesses.
That the seventh plague will indeed finish the anger of God upon the world is illustrated in the picture here given in Revelation. It indicates that those who survive the symbolic earthquake will without fail be destroyed by the accurately aimed executional hailstones from the heavens. Not that the truths themselves kill them, but the judgments that God executes in harmony with the truths expressed.—Job 38:22, 23; Ps. 148:7, 8; Isa. 28:2-17.
