What should Christians expect during the time before Christ's return?

In Mark 13, Jesus warns His followers to expect various forms of trials before His return. This includes deception from false prophets, wars, natural disasters, and personal betrayals, indicating that tribulations are part of the Christian's reality. However, He assures believers of His presence and the eventual triumph of His kingdom. These warnings prepare the Church to stand firm in their faith amidst adversity, recognizing that such struggles are part of the 'beginning of sorrows' preceding Christ’s glorious return.
