In her book To Fly Again, Gracia Burnham[1]quotes a devotional written by E. Stanley Jones, Methodist missionary to India. The devotional is entitled “Worry is Atheism.” Jones writes, 

A person who worries says, “I cannot trust God; I’ll take things into my own hands.” Result? Worry, frustration, incapacity to meet the dreaded thing when it does come. With God, you can meet it, overcome it, assimilate it into the purpose of your life. Alone, you fuss and fume and are frustrated.
