We hear of the conversion of water into wine at the marriage in Cana, as of a miracle. But this conversion is, through the goodness of God, made every day before our eyes. Behold the rain which descends from heaven upon our vineyards, and which incorporates itself with the grapes to be changed into wine; a constant proof that God loves us, and loves to see us happy!

Benjamin Franklin (1706-1790) American statesman, scientist, philosopher, aphorist

Apparent origin of the misquote: "Beer is proof that God loves us and wants us to be happy."
