27:31 {9} Paul said to the centurion and to the soldiers, Except these abide in the ship, ye cannot be saved.
(9) Although the performing of God's promises does not depend upon secondary causes, yet they make themselves unworthy of God's bountifulness who do not embrace those means which God offers them, either upon rashness or distrust.
27:30-32 As the shipmen were about to flee. The sailors were about to take the boat, under false pretense, and abandon the ship. For the safety of all it was needful that they remain, in order to manage the ship when it was run ashore. Hence the centurion, at Paul's request (Ac 27:31), cut off the boat and let it drift away (Ac 27:32).
27:31 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.
27:30-38 God, who appointed the end, that they should be saved, appointed the means, that they should be saved by the help of these shipmen. Duty is ours, events are God's; we do not trust God, but tempt him, when we say we put ourselves under his protection, if we do not use proper means, such as are within our power, for our safety. But how selfish are men in general, often even ready to seek their own safety by the destruction of others! Happy those who have such a one as Paul in their company, who not only had intercourse with Heaven, but was of an enlivening spirit to those about him. The sorrow of the world works death, while joy in God is life and peace in the greatest distresses and dangers. The comfort of God's promises can only be ours by believing dependence on him, to fulfil his word to us; and the salvation he reveals must be waited for in use of the means he appoints. If God has chosen us to salvation, he has also appointed that we shall obtain it by repentance, faith, prayer, and persevering obedience; it is fatal presumption to expect it in any other way. It is an encouragement to people to commit themselves to Christ as their Saviour, when those who invite them, clearly show that they do so themselves.
