There is nothing more dreadful than the habit of doubt. Doubt separates people. It is a poison that disintegrates friendships and breaks up pleasant relations. It is a thorn that irritates and hurts; it is a sword that kills. – Buddha
Whether your faith is that there is a God or that there is not a God, if you dont have any doubts you are either kidding yourself or asleep. Doubts are the ants in the pants of faith. They keep it awake and moving. – Frederick Buechner
