From lone preachers on street corners to great crusades in vast fields, the drive to preach God's Word to the whole world and bring as many into the church as possible has been a significant endeavor. Around the globe, many have adopted these models to reach the masses in far-flung nations, spreading the message far and wide. Jesus unambiguously commands in Mark 16:15, "Go into all the world and preach the gospel to every creature." He instructs the apostles in Luke 24:47 that repentance and remission of sins should be preached in His name to all nations, beginning at Jerusalem. In the Olivet Prophecy, Jesus prophesies, "And this gospel of the kingdom will be preached in all the world as a witness to all the nations, and then the end will come." God desires the good news that His Son brought to humanity to be proclaimed to everyone, making it a primary work of the church that Jesus founded and heads to this day. He tasked His apostles with spreading it worldwide, as seen in His directive to Paul through Ananias in Acts 9:15, "Go, for he is a chosen vessel of Mine to bear My name before Gentiles, kings, and the children of Israel." The apostles felt compelled to undertake this service for their Master with extraordinary drive, as Paul expresses in I Corinthians 9:16, "For if I preach the gospel, I have nothing to boast of, for necessity is laid upon me; yes, woe is me if I do not preach the gospel!" Jesus commands His church to preach the gospel, emphasizing its importance as a warning message of repentance and a call to turn from sin, preparing for the establishment of God's Kingdom. As stated in Matthew 24:14, the gospel serves as a witness, providing evidence and testimony about who God is, His standards, His actions, and the coming fulfillment of His purpose, ensuring humanity has no excuse when He brings justice to the earth.

The prophecy in Matthew 24:14 declares that the gospel of the Kingdom will be preached in all the world as a witness to all nations, and then the end will come. By the time Jesus Christ returns and the Millennium begins, this good news will have been proclaimed, ensuring that everyone on earth will have heard the message. Some will have repented, while others will have been destroyed, but the long-anticipated Kingdom will become a reality. This statement is a definitive future event, not an instruction, and it does not specify who will preach, how it will be done, or the timeframe involved, except that it occurs before the end. It simply assures that it will be accomplished, with only God knowing the exact means of fulfillment. The reality is that it is God who preaches the gospel, as seen in the ministry of Jesus Christ, who was sanctified and sent by the Father to proclaim this message. All of His words and actions, including His preaching, had their source in the Father. Regardless of the human instrument or method used, if God is not the Source, the work is merely human and in vain. The gospel is proclaimed through submission to God's leadership, not through human effort or will alone. God will ensure that the gospel of the Kingdom is preached as promised, through whatever means, agency, or time He has ordained. He controls the results and effects of His preaching, determining when and how it is prioritized. The question for us is whether we will align with Him and be usable by Him as He completes His work, letting Him lead rather than assuming we know His plans. Our focus should be on the sanctification He has given us, becoming spiritually worthy through submission to His will, so that we may be directed by Him in whatever capacity He chooses, large or small.

The concern about the gospel being preached around the world weighs heavily in assessing the timing of Christ's return. Some argue that Christ cannot return yet because the church has not fully witnessed to all the world. They believe a significant work remains for the church to accomplish in spreading the gospel globally before that day arrives. This perspective fuels the notion that the end may still be distant, as the mission to proclaim the message universally is seen as incomplete.

Some have been perplexed about the apparent paradox within Christ's Olivet Prophecy which, on one hand, describes the end time in human history—so severe that without the intervention of Almighty God, no flesh would survive. But, on the other hand, Christ compares those same days to the ordinary routines of Noah's and Lot's times, namely eating, drinking, marrying, buying, and selling, that is, life carrying on as if nothing were amiss. The paradox can be neutralized by realizing that Christ does not emphasize the prosperity but the suddenness of the destruction, striking when people least expect it. The paradox is also resolved when we realize the incredible ability of people to adapt to suffering such as the victims of the Warsaw Ghetto during WWII when people maintained a sense of "normal life" amid horrific conditions, some heroically, while others betrayed their fellow victims through compromise. Humans have an incredible resilience seeming "normal" even though tribulation. The true danger is not the result of human weapons or disasters, but Almighty God's "days of vengeance" on both Israel and the gentile nations for rebellion and oppression. In this context, unless God shortens those days, all flesh would perish. Adaptability can numb us to sin. Just as elites of the Warsaw Ghetto danced among the corpses, God's people tragically can adapt to lawlessness as their love turns ice cold. God's people must resist adapting to sin and spiritual complacency but stay ready for Christ's unexpected return.
