Some people say, "I used to evangelize many people. I was once a good church leader." Most of them say that they once did all that other Christians are doing, yet they do not try to learn good things from earnest Christians. That is why they cannot grow up in faith. If you think you are such a person, why don't you look back upon the time when you were filled with the Holy Spirit? In those days, you might have shed tears just seeing a cross on the street, or your heart may have fluttered in every worship service because you felt you were with the Lord. Recall and remember how you felt at those times, and you will be able to recover the earnestness in your believing life again.
