How terrifying it will be when God Himself causes this earth to tremble with His wrath. Israel was terrified when God gave His Law in peace; how horrifying will it be for the ungodly when He comes in wrath! That’s why we must reach out to them now. Paul said of his own motives, “Knowing, therefore, the terror of the Lord, we persuade men” (2 Cor. 5:11). Do we know the terror of the Lord—His just wrath against sin and the horrors of hell? If not, we will lack passion for the lost. Make sure you have a biblical understanding of the character of God. Smash any idols that may inhabit your mind. A god of only love and mercy, who is not also a God of wrath and judgment, is nothing more than a worthless idol.
“Good Mr. Whitefield used to cry, ‘Oh, the wrath to come! The wrath to come!’ And, verily, I know not what he could have said about it except to utter the exclamation—and there to leave it—for that wrath to come must surpass all human language or imagination!” Charles Spurgeon
Isaiah 13:11 “I will punish the world for its evil, And the wicked for their iniquity; I will halt the arrogance of the proud, And will lay low the haughtiness of the terrible.12 I will make a mortal more rare than fine gold, A man more than the golden wedge of Ophir. 13 Therefore I will shake the heavens, And the earth will move out of her place, In the wrath of the Lord of hosts And in the day of His fierce anger.
