I was trying to be flexible, but my mind was being stretched out of shape. Some days I would doubt the voice. It was, after all, in my head and talked a lot like me. But I was told,
My words are coming to you for a reason. Do not worry that it (My voice) sounds like you. It is bound to sound like you (and to use) your vocabulary, your concepts. That is how revelation works. But notice that what you are now writing is completely different from what you believed prior to prayer—so different, much of it is profoundly uncomfortable and disturbing to you.
“Well, then, it is not just my own thoughts projected through Your voice.”
As you press ahead and pray more, and read reverentially and in conversation with Me, more revelations will come to you, and you will doubt less. Just relax, and put yourself in My hands.
But being reassured by the very voice I was doubting seemed circular. How can you tell whether a message is really from God? Without mentioning my personal story, I sought advice from a philosopher I knew at Calvin College. Did he know of any writings about how to tell if an answer received in prayer is really from God. I learned that my question had an official name, the Problem of Spiritual Discernment, and that indeed it had been addressed. Now I would get to the bottom of it.
