We who preach (or teach or sing) use our voice a lot and sometimes misuse it. With time, we can begin to lose it. The "Berkeley Wellness Letter" of July, 2006, recommends getting medical advice if you lose your voice for more than two days, have a lump in your throat or difficulty swallowing, or if hoarseness persists for two weeks. If the problems continue, you may need to work with a voice therapist. I have known good men who have struggled greatly with this problem. Please take it seriously. Your voice is one of the most important tools in your ministry. If you have a continually strained voice, check with your physician or the American Speech-Language-Hearing Association for a referral.
