2 Corinthians 1:8 & 9
We do not want you to be uninformed, brothers and sisters, about the troubles we experienced in the province of Asia. We were under great pressure, far beyond our ability to endure, so that we despaired of life itself. Indeed, we felt we had received the sentence of death. But this happened that we might not rely on ourselves but on God, who raises the dead.
Paul is probably talking about his adventure of faith in Lystra where he was taken out and stoned. He reminds the believers that no man has the power to overcome the plan of God. It was not his time to go to heaven so, even after being stoned, he got up again. We must remember that nothing has the power to defeat a man that is following the will of God for their life. He has numbered our days and He is in charge.
