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.
