What does the Bible say about the church in tribulation?

The church in tribulation is a recurring theme in Scripture, particularly seen in the experiences of early Christians as they faced persecution for their faith. In 2 Thessalonians 1, Paul discusses the suffering faced by the Thessalonian believers and assures them that this persecution is a 'manifest token of the righteous judgment of God' (2 Thessalonians 1:5). This suffering not only indicates their worthiness for God's kingdom but also serves to glorify Christ through their endurance. As they suffer for the sake of the Gospel, they follow in the footsteps of Christ and witness to the truth of their faith in a hostile world. Historically, the suffering of the church often results in growth, both spiritually and in numbers, as seen with the early church's expansion even amidst fierce persecution.
