The prophecies concerning Jesus Christ's return, often referred to as the "coming of the Son of Man," are central to understanding the Day of the Lord, a time of God's vengeance. This phrase, appearing in various forms such as "before the Son of Man comes" or "the Son of Man coming," is predominantly found in the Olivet Prophecy across Matthew 24, Mark 13, and Luke 21, as well as in parables like the Wise and Foolish Virgins in Matthew 25:13 and the Unjust Judge in Luke 18:8. These references point to a future event characterized by divine wrath, distinct from the destruction of Jerusalem in AD 70, which does not align with the apocalyptic imagery of clouds and redemption described in Luke 21:25-27. Christ Himself connects His return to the days of vengeance, emphasizing that all written prophecies will be fulfilled during this period, as stated in Luke 21:22. The Day of the Lord is understood as a year-long period of great wrath, culminating in Christ's return to rule at its conclusion. At this time, as described in Revelation 11:15-19, the kingdoms of this world will become the kingdoms of our Lord and of His Christ, and He shall reign forever. Following this, He will establish Jerusalem as a city of worldwide acclaim, regather scattered Israel, draw all peoples to Himself, and teach the law from Zion. This marks the beginning of the Millennium, a time of peace distinct from the destruction of the Day of the Lord. The prophetic timeline places the Day of the Lord as the final year of the Time of Jacob's Trouble, ending with Christ's revealing and the fulfillment of God's vengeance as foretold to the prophets.

The return of Jesus Christ is a central hope and a pivotal event in history, long proclaimed by the church since its founding. We yearn for His coming, believing He will return in great power and glory to defeat His enemies and establish His Kingdom on earth. This second coming, anticipated since the apostles' time as seen in their questions to Him before His ascension, marks a dramatic shift from humanity's disastrous self-rule to the blessed rule of God. As Peter preached, God will send Jesus back to inaugurate the times of restoration, a theme echoed since the world began through God's holy prophets. The hope of Christ's return permeates nearly every page of the New Testament and many in the Old Testament, culminating in Revelation with His declaration, "I come quickly." The Feast of Trumpets, a holy day, prefigures this event with the blowing of trumpets, signaling a call to attention for a momentous occurrence. This day of proclamation ensures the whole world will know of His return, with no one able to plead ignorance, as depicted in Revelation where every eye will see Him, accompanied by loud voices, trumpets, and heavenly signs announcing His reign. Christ's return is described as unmistakable and explosive, a time of great opposites—war bringing peace, death opening life, dread ushering hope, and destruction leading to restoration. It will force all to react, whether negatively or positively, as it unfolds front and center with lightning-like suddenness, darkening skies, and a great trumpet blast gathering His elect. He will come in His Father's glory, with a multitude of angels, His face shining like the sun, to reward His followers and judge His enemies, as seen in the Transfiguration's glimpse of His future majesty. Jesus Himself spoke of His return, teaching in the Model Prayer to pray daily for the Kingdom to come, indicating a future time of power and glory. He described His coming as the regeneration, a new beginning when He sits on His throne, rewarding His followers with positions of authority and eternal life. He prepares a permanent place for His people in His Father's house, ensuring they will be with Him forever, received into His Family upon His return. In His Olivet Prophecy, Jesus outlined the end times, warning of great tribulation and deception before His return, which will be sudden and visible to all, like lightning flashing across the sky. He cautioned against false claims of His presence, urging vigilance. He stressed the importance of readiness, as no one knows the hour of His coming, only that it will seem delayed to us, requiring constant watchfulness and faithfulness in spiritual growth to avoid squandering His grace. In hope of His arrival, we must diligently apply ourselves to God's way of life, ever preparing for that Day.

Scoffers in the last days mock the promise of Jesus Christ's return, questioning, "Where is the promise of His coming?" They argue that since all things continue as they were from the beginning of creation, there is no reason to expect a cataclysmic event. Yet, their presence is itself a sign of the approaching last days, as foretold by the apostles. These mockers, walking after their own lusts, ridicule the predictions of Christ's return, the day of judgment, and the world's destruction by fire, denying the truth of God's Word. The certainty of Christ's return in glory is affirmed, despite the scoffers' denial. The Day of the Lord, a time of judgment, will culminate with Jesus Christ returning to earth in victory. This day, also linked to the time of Jacob's trouble and the tribulation, will be a period when God's wrath is poured out on the nations. It will come as a thief in the night, unexpected by the world, bringing sudden destruction when people feel secure in their own destiny. The heavens will pass away with a great noise, the elements will melt with fervent heat, and the earth and all its works will be burned up. God's Word stands true, as spoken by the prophets, Jesus Christ, and the apostles, united in their message about the coming judgment. The delay in Christ's return is not a sign of slackness but of God's longsuffering mercy, as He desires that none should perish but that all should come to repentance. With the Lord, a day is as a thousand years, and a thousand years as a day; He is not bound by human time, and His plan unfolds according to His will. The Day of the Lord will surely come, a day of darkness and terror for the wicked, when God will punish the world for its evil and destroy the works of man in an instant. This promise of judgment and Christ's return is a call to awaken from spiritual lethargy and live godly lives. The world, groaning under the weight of sin, awaits the revealing of the sons of God and the establishment of a glorious Kingdom. God's intervention in history, as seen in past events like the Flood, proves His power to act again. The scoffers' willful ignorance cannot negate the reality that the heavens and earth are reserved for fire until the day of judgment, when Christ will return to fulfill every promise of God.
