Will there ever be peace across the globe? Matthew 24:6 indicates that there will always be wars and rumors of wars. In Matthew 24, it speaks of persecution against the church. What Jesus says is an accurate predictor of the beginning of the end times. It should spur you on to being a witness of the gospel. As vs. 14 states: "And this gospel of the kingdom will be proclaimed throughout the whole world as a testimony to all nations, and then the end will come."
Even though there may not be a worldwide peace until Jesus returns to establish His millennial Kingdom, James 3:18 will become a reality. As people of peace share their faith, and those hearing their witness make peace with God, the lights of their good deeds will shine in an ever-widening harvest of righteousness.
