How do we know that suffering is part of the Christian life?

The concept of suffering being central to the Christian faith is not only established by Christ's own life but also by the teachings of the Apostles. Jesus Himself made it clear that suffering and hardships are part of the believer's journey, as exemplified in His own sacrifices and trials (1 Peter 2:21). Paul reflects on this conflict in Romans 7, revealing the internal struggle of sin versus righteousness, which highlights the necessity of relying on Christ for strength. As Christians, we are called to endure suffering patiently, as it brings us closer to Jesus and ultimately fulfills God's purposes in our lives (Romans 8:28-30).
