William Burkitt on 2 Corinthians 1:9

Observe here, The great and imminent danger which the apostle was in: his very life was in a hazard, nay, even despaired of; he looked upon himself as a dead man: but when he had thus sentenced himself, a divine power, which wrought above all his thoughts and rational conjectures, reprieved him, and revived him.

Hence learn, that the almighty power of God sometimes works beyond all creature expectations, beyond all human probabilities, beyond all rational conjectures, to help and deliver his people in hopeless and helpless trouble.
