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

Suffering is a prominent theme throughout Scripture, particularly in the life of Peter and the early church. In 1 Peter 1:6-7, Peter writes about trials that prove the genuineness of faith, likening it to gold being tested by fire. The call to follow Christ inevitably includes embracing suffering, as modeled by Jesus Himself who endured immense hardship and ultimately martyrdom. In John 21:18-19, Jesus foretells Peter's own suffering, indicating that true following of Christ may lead to paths we would not choose for ourselves. This suffering is not purposeless but is a tool used by God for sanctification, ultimately glorifying Him and preparing believers for eternity.
