Wow My mom and dad where in the deaf ministry and signing when I was a kid, We were baptist so the signing was very text book. So imagine you see on tv the evangelist preaching a powerful sermon such as at a revival then imagine you didn't get to see the sermon spoken you simply had to rely on reading it. This is often the way I see how deaf people must get church. I came across the above video of a guy interpreting the song "heart of Worship, and I think If I were deaf and watching I would get it as its meant to be gotten. So watch I think the passion comes thru.
Watch the one above and then this one is as good
