Music is often a source of controversy in churches today, and no matter what I say in answer to your question, I’m sure some will disagree!
My own view, however, is that churches should try to minister to all their members–including both youth and older people. In our own missions in recent years we have included much more contemporary music (especially on youth nights, but at other times as well). At the same time, we also include more traditional music. Perhaps you can suggest to your pastor that he use various kinds of music in your services.
Yes, of course you have spiritual needs as an older person, and God wants to meet those needs by helping you grow spiritually. The Bible says, “grow in the grace and knowledge of our Lord and Savior Jesus Christ” (2 Peter 3:18). If God’s Word is being preached and taught in your church, God will use it to help you become spiritually strong. Ask Him to help you overlook any music you don’t like and focus instead on Christ and His Word.
Pray for your pastor–not just that he will be sensitive to your needs, but that God will help him reach young people for Christ. Can you think of any greater need in today’s confused world?
