Peter could speak credibly about persecutions because he endured them himself. He practiced what he preached (1Pet 4:12-14).
Peter’s message is more reliable because he backed it up with his life.
Leader, do others take your requests seriously?
If not, check your life to see if you are doing what you ask others to do. Do you have credibility?
