Ever ask the question why? In 2 Corinthians 1 Paul is speaking about his sufferings in the province of Asia which were far beyond his ability to endure, so that he and the others despaired even of life.
Instead of asking why, Paul states a Biblical truth. But this happened that we might not rely on ourselves but on God, who raises the dead. 3 quick comments.
1. Paul is satisfied with this answer. He did not need to know the details, he simply needed to know God was present. As you ask why in your circumstances, would you be satisfied with this answer?
2. Paul knows his heart - he can easily begin to rely on himself - and so can we in our circumstances. Our God is so amazing He knows when we are becoming to self reliant and we need to focus our lives and trust on Him. And so Paul's statement of Biblical truth is really and submissive prayer of thanksgiving for God's Fatherly care.
3. Paul confesses a powerful God. We do not rely on a weak and powerless God but a God who raises the dead. Paul felt the sentence of death (verse 9a) but guess what - God is able to raise the dead. You may feel the sentence of death, as if God has abandoned you or left you to die. But God, in His power, raises the dead and displays His glory through your life.
With this confession, Paul concludes His unfailing trust in God that He will continue to deliver them and all God's people. That is what Biblical truth does - gives hope to go on as we daily die to self. Are you "under the sentence of death"? Maybe God is taking your eyes of you and placing them on His power and promises. That, believer, is a far better place to be.
