Water and petrol both come from the earth, and though they seem to be alike and even the same, they are in nature and purpose exact opposites, for the one extinguishes fire and the other adds fuel to it. So also the world and its treasures, the heart and its thirst for God are alike His creation. Now the result of the attempt to satisfy the heart with the wealth and pride and honours of this world is the same as if one tried to put out a fire with petrol, for the heart can only find ease and satisfaction in Him who created both it and the longing desire of which it is conscious.
