I remember several years ago, waking up in the middle of the night. Suddenly, I was led to pray for my grandfather. There was no audible voice, but the message was clear.
I had no detail on why I was supposed to pray, but when I did, I felt peaceful and had a strong impression that the prayers were important and were accomplishing something. I prayed with my understanding as well as with my spirit. After awhile, I relaxed and fell back to sleep.
The next day, I received word that my grandfather had suffered a heart attack. He was stable and ultimately recovered and lived for many more years. When I learned that the attack occurred around the time I was awakened in the night, I was amazed and thankful. I praised God for working to help my grandfather and began to learn about the importance and power of our prayers.
