Acts 27:31 - Wesley's Explanatory Notes

Unless these mariners abide in the ship — Without them ye know not how to manage her, ye cannot be saved — He does not say we. That they would not have regarded. The soldiers were not careful for the lives of the prisoners: nor was Paul careful for his own. We may learn hence, to use the most proper means for security and success, even while we depend on Divine Providence, and wait for the accomplishment of God's own promise. He never designed any promise should encourage rational creatures to act in an irrational manner; or to remain inactive, when he has given them natural capacities of doing something, at least, for their own benefit. To expect the accomplishment of any promise, without exerting these, is at best vain and dangerous presumption, if all pretence of relying upon it be not profane hypocrisy.
