When Christ ceases His intercession in the sanctuary, the unmingled wrath threatened against those who worship the beast and his image and receive his mark (Revelation 14:9, 10), will be poured out. The plagues upon Egypt when God was about to deliver Israel were similar in character to those more terrible and extensive judgments which are to fall upon the world just before the final deliverance of God's people. Says the revelator, in describing those terrific scourges: “There fell a noisome and grievous sore upon the men which had the mark of the beast, and upon them which worshipped his image.” The sea “became as the blood of a dead man: and every living soul died in the sea.” And “the rivers and fountains of waters ... became blood.” Terrible as these inflictions are, God's justice stands fully vindicated. The angel of God declares: “Thou art righteous, O Lord, ... because thou hast judged thus. For they have shed the blood of saints and prophets, and thou hast given them blood to drink; for they are worthy.” Revelation 16:2-6. By condemning the people of God to death, they have as truly incurred the guilt of their blood as if it had been shed by their hands....
In the plague that follows, power is given to the sun “to scorch men with fire. And men were scorched with great heat.” Verse 8-9....
These plagues are not universal, or the inhabitants of the earth would be wholly cut off. Yet they will be the most awful scourges that have ever been known to mortals. All the judgments upon men, prior to the close of probation, have been mingled with mercy. The pleading blood of Christ has shielded the sinner from receiving the full measure of his guilt; but in the final judgment, wrath is poured out unmixed with mercy.47The Great Controversy, 627-629.
The bolts of God's wrath are soon to fall, and when He shall begin to punish the transgressors, there will be no period of respite until the end. The storm of God's wrath is gathering, and those only will stand who are sanctified through the truth in the love of God. They shall be hid with Christ in God till the desolation shall be overpast.48Testimonies to Ministers and Gospel Workers, 182. Mar 267
We should not take the testimony of any man as to what the Scriptures teach, but should study the words of God for ourselves. If we allow others to do our thinking, we shall have crippled energies and contracted abilities. The noble powers of the mind may be so dwarfed by lack of exercise on themes worthy of their concentration as to lose their ability to grasp the deep meaning of the word of God. The mind will enlarge if it is employed in tracing out the relation of the subjects of the Bible, comparing scripture with scripture and spiritual things with spiritual. SC 89
And I heard a great voice out of the temple saying to the seven angels, Go your ways, and pour out the vials of the wrath of God upon the earth. Revelation 16:1. KJV
