1 Peter 5:10

¹⁰ And the God of all grace, who called you to his eternal glory in Christ, after you have suffered a little while, will himself restore you and make you strong, firm and steadfast.

Does this still apply if I suffer because of my own fault and sin?

Self prophecy

A man tirelessly campaigns for safety improvements in his local neighborhood. A nearby intersection is a death black spot. He warns that if the local government does not take any action, there will soon be another death on the road. Not long after his prophecy is fulfilled. He is tragically killed in a car accident on the very road.
