What does the Bible say about enduring tribulation?

In 2 Corinthians 4:16, the Apostle Paul encourages believers not to lose heart despite outward tribulations, as our inner being is renewed daily. This renewal of the inward man signifies that while we may experience physical decay, our spiritual vitality grows as we rely on God's grace. The Apostle Paul illustrates that our hope extends beyond this life, pointing to eternal glory that far outweighs our momentary afflictions. Such an understanding empowers Christians to face trials with a sense of purpose, knowing that these sufferings ultimately contribute to our spiritual growth and further glorify God.
