Simplicity is the secret to seeing things clearly. A saint does not think clearly until a long time passes, but a saint ought to see clearly without any difficulty. You cannot think through spiritual confusion to make things clear; to make things clear, you must obey. In intellectual matters you can think things out, but in spiritual matters you will only think yourself into further wandering thoughts and more confusion. If there is something in your life upon which God has put His pressure, then obey Him in that matter.
