How do we know that suffering for righteousness is a part of the Christian calling?

In 1 Peter 2:21, Peter explains that we are called to suffer for doing good, just as Christ also suffered for us, leaving us an example to follow. This calling to endure hardships and opposition is rooted in our identification with Christ’s sufferings. Believers face various trials, not as a curse, but as a means to participate in the redemptive work of Christ. The call to such suffering is confirmed by Christ himself, who promised that his followers would face persecution for His name’s sake, as noted in John 15:20-21.
