Genesis 32:13

13.And took of that which came to his hand. In endeavoring to appease his brother by presents, he does not act distrustfully, as if he doubted whether he should be safe under the protection of God. This, indeed, is a fault too common among men, that when they have prayed to God, they turn themselves hither and thither, and contrive vain subterfuges for themselves: whereas the principal advantage of prayer is, to wait for the Lord in silence and quietness. But the design of the holy man was not to busy and to vex himself, as one discontented with the sole help of God. For although he was certainly persuaded that to have God propitious to him would alone be sufficient, yet he did not omit the use of the means which were in his power, while leaving success in the hand of God. For though by prayer we cast our cares upon God, that we may have peaceful and tranquil minds; yet this security ought not to render us indolent. For the Lord will have all the aids which he affords us applied to use. But the diligence of the pious differs greatly from the restless activity of the world; because the world, relying on its own industry, independently of the blessing of God, does not consider what is right or lawful; moreover it is always in trepidation, and by its bustling, increases more and more its own disquietude. The pious, however, hoping for the success of their labor, only from the mercy of God, apply their minds in seeking out means, for this sole reason, that they may not bury the gifts of God by their own torpor. When they have discharged their duty, they still depend on the same grace of God; and when nothing remains which they can attempt, they nevertheless are at rest.
