COPY OF STORY FOLLOWS:
I was very upset about a personal situation that was causing me much pain and suffering. I had begun to worry about it so much that, on this particular morning, I'd worked myself into a state of sheer panic. My heart was pounding so hard I thought I would have a heart attack. I was pacing the floor, unable to stay calm and praying very hard to God that he would help me with this situation. At first I was praying for relief from the problem, but soon began praying that God would help me calm down physically. I knew my body could not sustain this severe stress response much longer.
I paced into my kitchen (I was home alone) and stared out the window into the sky praying and begging for relief. All of a sudden and out of the blue a perfect calm descended on me and I heard these simple words clearly in my head: "IT IS NOT TIME. JUST BE."
From that time on I was fine--perfectly calm and my heart stopped racing. I was almost happy, even. It was simple, yet amazingly profound. I knew everything was ok.
I felt that God had taken pity on my distraught condition and loved me enough to help me. I assume it was the voice of the LORD, but it could have been an angel or some other heavenly being. I just don't know. But it was from outside myself, yet was heard within my own mind.
The problem did not spontaneously resolve that day, or in the weeks after, but my worry and stress did. I thank God for His love and mercy to me.
Just for clarification, I am perfectly sane, free of mental problems, and have never before or since heard a voice in my mind. (And don't expect to.)
