What does the Bible say about Christian suffering and persecution?

In Mark 13:9-23, Jesus warns His disciples about the inevitable troubles they will face due to their commitment to the Gospel. Believers are warned that they will encounter hostility from the world, including imprisonment and judgment, purely because of their adherence to Christ. Additionally, familial betrayals may occur, where even close relations can turn against them. This expectation is rooted in the understanding that the offense of the cross persists through all ages, leading to genuine discomfort for true followers of Christ. The passage encourages Christians to count the cost of discipleship, reminding them that hardships can accompany a life devoted to Christ.
