"... the Lord has furnished men with the arts of deliberation and caution, they they may employ them in subservience to his providence, in the preservation of their life; while, on the contrary, by neglect and sloth, they bring upon themselves the evils which he has annexed to them. How comes it that a provident man, while he consults for his safety, through unadvised temerity, perishes, unless it be that prudence and folly are, in either case, instruments of divine dispensation? God has been pleased to conceal from us all future events that we may prepare for them as doubtful, and cease not to apply the provided remedies until they have either been overcome, or have proved too much for all our care. Hence, I formerly observed, that the Providence of God does not interpose simply; but, by employing means, assumes, as it were, a visible form."
John Calvin, Institutes of the Christian Religion, Book 1, Ch. 18 (1559).
