The following is an piece of an article written by Splinter's of Silver. It is a brilliant post and all Christians should take a look at this one....
"The thing I would like to ponder is the idea of children verses adult singing specials in the church. In fact, I’ll just come right out and ask the question:

It goes on to cover an issue that I had previously not even thought of. Go read it.
