Jesus gave many prophecies about the future and His return. He said that no one knows the day nor the hour of His second coming, yet we are to watch for the signs of the times and make sure that when He comes, He will find us faithfully serving Him. When Jesus was arrested and crucified, all of His disciples fled, but they came back together after His resurrection. He then commissioned them to go into all the world and make disciples.
