Thought of the Day
30 Questions, 30 Class Periods, 30 Answers
It wasn’t unusual for a student to drop into my office,...but this student’s reason for dropping in was unique.
The student began by saying, “I thought you would be interested in knowing how your class has helped me. I enjoyed studying the Book of Mormon, but I also had some problems I needed help with. So I came up with a plan. I wrote down a question for each class period. Then I prayed about the question and went to your...class.”
The young man showed me the questions he had written down: 30 questions, 30 class periods, 30 answers. I noticed that many of the answers to his questions had nothing to do with the material I had been teaching! But this student had sought the Lord in prayer and had come in faith to my class, expecting the answers. And he had received an answer to every question! I realized that the Spirit had led him to find the answers to his questions.
