I've seen a few people suggest that it's from the early 80s - it definitely sounds like young Whitney and she would have been 16/17 in 1980, so I believe it.Do we know when this was recorded? Her voice sounds different. Is it very early in her career?
The song itself is really great too! It's funny to me that I'm not typically a worship music person, nor am I especially religious these days, but when you have a voice like Whitney's doing gospel it doesn't even matter.
