All Things Are Possible to Them That Believe by Annie Rix Militz.
WHEN the disciples of Jesus asked, "What must we do that we may work the works of God?" all the reply that Jesus gave was, "Believe," and this was the substance of all his instruction. Set your thoughts in a certain direction; make your mind to hold thoughts that believe in the Good as possible. That is all that is necessary for us to do to increase our belief, to extend the boundaries of what we believe to be possible.
All that we are now is the result of our believing; every action and word shows forth what we have been believing, and are now holding in mind.
When you lie down at night you believe you will arise in the morning; when you walk, every step you take you do so through the exercise of faith, believing that you will be supported: so all things that you do are simply pictures of your faith, or what you are believing in.
