What would you think if someone said to you with a completely straight face, “We need to talk”? That phrase tends to make people nervous—you immediately wonder what you did wrong, what bad news is coming. That’s exactly the feeling the Day of the Lord is meant to evoke. In 2 Thessalonians chapter 2, Paul writes about this future event—but as Pastor Josh White unpacks it, this is not a passage to read lightly. The Day of the Lord is not good news. It is bad news.
So why would God tell us about it? Because His desire is exactly the opposite: He wants everyone to be saved.
“This is good, and it is pleasing in the sight of God our Savior, who desires all people to be saved and to come to the knowledge of the truth.”
— 1 Timothy 2:3-4
God shows His love for us in that while we were still sinners, Christ died for us (Romans 5:8). But God has also revealed that a day is coming when He will judge mankind for their wickedness. That day is called the Day of the Lord—and it is the most loving thing God could tell us, because it is a warning meant to drive us to repentance and faith in Jesus Christ.
Why Will the Day of the Lord Happen?
Paul makes clear in 2 Thessalonians 2:1-5 that this day will not come until two events take place first: the Rebellion and the revealing of the man of lawlessness. But setting the timing aside, the Bible gives us two primary answers to why God will pour out His wrath on mankind.
Purpose #1: To Punish Evil
God’s holiness demands payment for sin. Romans 1:18 says it plainly: “The wrath of God is revealed from heaven against all ungodliness and unrighteousness of men, who by their unrighteousness suppress the truth.” This phrase—the Day of the Lord—appears 19 times in the Old Testament alone, and is also referred to as the Day of God’s Wrath, the Tribulation, and the Day of Jacob’s Trouble.
During this seven-year period (the 70th week of Daniel’s prophecy), God will unleash judgment after judgment upon the earth. Revelation 8 describes the seven trumpet judgments—hail, fire, and blood destroying a third of the earth and all the trees. The seven bowl judgments that follow (Revelation 16) pour out God’s full wrath on rebellious mankind.
“Woe to you who desire the day of the Lord! Why would you have the day of the Lord? It is darkness, and not light.”
— Amos 5:18
The Isaiah passage paints a vivid picture of devastation. The sun will be darkened. The moon will not shed its light. Stars will fail to give their light. The earth will shake. Mass casualties will result from God’s judgment on human wickedness.
“Behold, the day of the Lord comes, cruel, with wrath and fierce anger, to make the land a desolation and to destroy its sinners from it.”
— Isaiah 13:6, 9
But this isn’t just destruction for destruction’s sake. Isaiah 2:12 and 2:17 explain the purpose: God will bring low every proud and lofty thing. Man’s arrogance will be humbled. The lofty pride of men shall be brought low, and the Lord alone will be exalted in that day.
“Stop regarding man, in whose nostrils is breath, for of what account is he?”
— Isaiah 2:22
God is teaching all mankind a lesson: stop trusting in man. Politicians, business leaders, celebrities—none of them can save anyone. Only the holy, righteous Creator of the universe holds that power.
Purpose #2: To Prepare the Earth for What Is Next
God has done this before. In Genesis 6, God saw the wickedness of man was great and that every intention of his heart was only evil continually. He said, “I will blot out man whom I have created from the face of the land.” But in His mercy, He saved Noah—a righteous man—and through the flood, He cleansed the earth and prepared it for repopulation and, eventually, for the coming of the Messiah.
Similarly, in Deuteronomy 9, God drove out the wicked nations inhabiting the Promised Land so that Abraham’s descendants could live righteously before Him. He told Israel explicitly: “Not because of your righteousness or the uprightness of your heart are you going in to possess their land, but because of the wickedness of these nations that the Lord your God is driving them out before you” (Deuteronomy 9:5).
The Day of the Lord follows this same pattern. God will punish evil mankind and prepare the earth for the return of the King. Acts 3 confirms this: Peter preached that the nation of Israel must repent so “that the times of refreshing may come from the presence of the Lord and that He may send the Christ appointed for you, Jesus” (Acts 3:19-20). God is preparing a cleansed earth for Christ’s millennial kingdom—His throne forever promised to David.
“But that day of the Lord will come like a thief, and then the heavens will pass away with a roar, and the heavenly bodies will be burned up and dissolved, and the earth and the works that are done on it will be exposed.”
— 2 Peter 3:10
When Will It Happen?
No one knows. The timing is deliberately hidden from us. Jesus Himself said only the Father knows the day and hour (Matthew 24:36). But the Bible tells us two things must happen first: the Rebellion and the revealing of the man of lawlessness. Those events will be the signal that the countdown has begun.
But there is comfort for believers: “Because God has not destined us for wrath, but to obtain salvation through our Lord Jesus Christ” (1 Thessalonians 5:9). We are not destined for the Day of the Lord. That is good news.
How Should We Respond?
Pastor Josh closed with a challenge that ties directly to what is ahead for Grace Bible Church. If God’s future wrath is real and coming, and if today is the day of salvation (2 Corinthians 6:2), then our response must be urgent.
Be grateful. Not only do we get what we don’t deserve—eternal life—but God has promised to deliver us from the coming wrath. We are of the light, not of the darkness.
Share the gospel with urgency. People we know and love are in danger of enduring God’s wrath unless they put their faith in Jesus Christ. This is why the church exists—to declare the good news that salvation is available today.
This is especially front of mind as Easter approaches at GBC Phoenix. Looking ahead to Resurrection Sunday weekend, the church will host a 40-hour prayer event bridging Good Friday and Easter morning, along with a 40-hour fast for anyone who wishes to participate. Two Easter services will be held to create room for guests. The weekend is designed not only to remember Christ’s death and celebrate His resurrection, but to intentionally invite friends, family, and neighbors who need to hear the message of salvation.
What better Sunday to invite someone to church than Easter?
The Day of the Lord is coming. It will be heavy. It will be devastating. But it is a reminder that God’s holiness demands justice—while at the same time, His grace has provided the way of escape. Today is the day of salvation. May God use us to make the most of it.
