For right reasoning there should be but one fact before the thought, namely, spiritual existence.
~ Mary Baker Eddy, Science and Health with Key to the Scriptures, p. 492
If you want to end up in the right place it helps to start from the right place.
As a child of God, you are a spiritual being. Reason out from Spirit, not from matter, and you’ll sooner understand who you are and what you’re all about.
Reason rightly. From Spirit.
