acts 14:17 Nevertheless he left not himself without witness, in that he did good, and gave us rain from heaven, and fruitful seasons, filling our hearts with food and gladness. - Free Bible Online

      17. Nevertheless he left not himself without witness--Though the heinousness of idolatry is represented as so much less in the heathen, by how much they were outside the pale of revealed religion, he takes care to add that the heathen have divine "witness" enough to leave them "without excuse."
      he did good--scattering His beneficence everywhere and in a thousand forms.
      rain from heaven, and fruitful seasons--on which human subsistence and all human enjoyment depend. In Lycaonia, where, as ancient writers attest, rain is peculiarly scarce, this allusion would have all the greater effect.
      filling our hearts with food and gladness--a natural colloquialism, the heart being gladdened by the food supplied to the body.
