I've only recently joined a United Church but what I like about it is that it is in a small, pleasant building near where I live.  The people are friendly and welcoming.  Most of them are not of my generation but I am alright with that.  The messages have been interesting and enlightening, though I was troubled by some of what was spoken, and the music pleasant and largely new to me.

On another topic, I checked out the first link from the other fellow who apparently is Muslim.

There is nice music and some history on the Islamic prophet but I found conflicts between what is believed by Islamists and the Hebrew scripture, even among the details about Abraham and Sarah.  Ah well.
