Wars and rumors of wars are mentioned as warnings, but they are just signs of what is to come, not indications that the end times have arrived. Jesus taught that conflicts and wars are part of human existence and should not be viewed as signs of the end of the age (Matthew 24:6). Wars, along with other events like famine and earthquakes, are "the beginning of birth pains" (Matthew 24:8). While wars will continue throughout history, including more catastrophic ones in the end times, Jesus instructs believers not to be alarmed by them. Believers are to focus on living for Christ, in war or out of war, knowing that the end will come when the gospel is proclaimed to all nations (Matthew 24:14).
Wars will still occur in the end times. In fact, some very catastrophic wars take place at the end of the age that will overshadow anything we have experienced thus far. Until Jesus brings eternal peace for individuals and for nations in the Millennial Kingdom, there will always be war. We need not panic at every war and rumor of war. In fact, Jesus told His followers not to be alarmed by these things.
Rather than worry about the wars raging in the Middle East, in Eastern Europe, and elsewhere, we must keep our eyes fixed on Jesus and obey Him. He has given us a mission to fulfill (Matthew 28:18-20). When telling His disciples about the signs of the end, He said, "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" (Matthew 24:14). Living for Him, reflecting Him, and sharing the gospel should be our focus.
