poison Satan produces, God turns it into medicine for his elect." John
Calvin commenting on Gen 50:20"...yet... [God] turns the food of
reprobates into poison, their light into darkness, their table into a
snare, and, in short, their life into death. If human minds cannot reach
these depths, let them rather suppliantly adore the mysteries they do
not comprehend, than, as vessels of clay, proudly exalt themselves
against their Maker." via. Manuel K.
