What does the Bible say about being called as a Christian?

In 1 Peter 2:21, we see that believers are called to follow in the footsteps of Christ, who suffered for us. This calling is not limited to comfortable circumstances but extends to how we respond in trials and tribulations. Christians must live in a manner that reflects their identity as children of God, embodying patience and righteousness, even when facing unjust treatment. Peter emphasizes that believers are indeed 'strangers and pilgrims' in this world, indicating that our true citizenship is in Heaven, which shapes how we conduct our lives on earth.
