I withheld thee, &c. It is God that restrains men from doing the ill they would do; it is not from him that there is sin, but it is from him that there is not more sin, either by his influence on men's minds, checking their inclination to sin, or by his providence, taking away the opportunity of committing it. It is a great mercy to be hindered from sinning, which God must have the glory of, whoever is the instrument.
