You obviously grew up in church. Many don’t, and to them hymns are barely recognizable. I didn’t grow up in church myself, and as a result I have no ear for hymns. To be honest, when I do visit a church that sings traditional hymns, I tune them out. They’re really something you need to grow up with to appreciate.
My grandmother was the regular church organist from the time she was 12 years old till she was in her 80s.
On the basic subject, I heard today how many people got saved in our church last week. The service I attended had an incredible response, as did the other ones. But our pastor was explaining that a number of people commented they had no idea that Easter had anything to do with the Resurrection of Jesus. He discussed how we should never assume people understand even the basics.
