What does the Bible say about suffering for the gospel?

In Revelation 1:9, the Apostle John identifies himself as a brother and companion in tribulation, emphasizing that suffering is a common aspect of the Christian experience. Throughout the New Testament, believers are encouraged to view their trials as a means to share in the sufferings of Christ. John's exile was due to his testimony of Jesus and the Word of God, reflecting the reality that proclaiming the gospel often leads to persecution and hardships. However, amidst suffering, believers are reminded to focus on Christ, who is the source of their strength and hope.
