“[…] Jehovah knows how to rescue people of godly devotion out of trial […].”
~2 Peter 2:9

Peter knew he would die the death of a martyr, but this did not weaken his faith in Jehovah. (John 21:18; 2 Pet. 1:13-15)
He put his trust in God’s undeserved kindness and the transcendence of divine justice. (2 Pet. 1:2; 3:13,18)
We may end up in a painful life situation where we know we are to endure a strenuous trial in the near future.
This might be due to health issues or other unfair circumstances.
If we are convinced of Jehovah’s love for us, we can face our trials with courage, and we will never lose hope in God’s promises. (Rom. 8:35-39; 2 Pet. 1:10,11)
