Question yourself as to whether this faith is within you, or perhaps you are led by worldly wisdom. And if you leave all things in the hands of God, behold! You have acquired faith and undoubtedly, without any question, you will find God to be your helper. And so, even should you be tried a myriad of times and should satan tempt you to abandon faith, prefer death a thousand times more and don’t obey worldly wisdom. In this way the door of the mysteries will be opened to you and you will be amazed how the chains of worldly wisdom previously bound you. Now you will fly with divine wings above the earth and breathe the new air of freedom, which, of course, others are deprived of. If, however, you see that within you, you are governed by worldly wisdom, and in the smallest danger you lose hope and despair, know that you have not yet acquired faith, and consequently also hope, in God.
