Not beeing christian, the lyrics mean zip to me, so I can't comment on those. I can however, comment on the musical aspect:
Who you are:
More than a good song. Good production too. Female vocals could use more emotion, and the climax could be a bit bigger. The male vocals are really not my thing.
Never changing:
Snare sounds too far away (sound like the recording room is not completely dry?). About the song itself: same story. Nice, but please don't let the other songs be of the same stuff.
Stellar:
Ah, thank you, acoustical guitar. Ok, it's pretty clear the production is gonna be pretty good through out the album. Try to make the drums a bit less dry on every song, especially the snare sounds boxy to me.
Rest of the songs:
In a nutshell, you seem to get the basic idea of how to write a song, but that's just what they are, songs, and nothing more. They don't my make skin tingle or even put a smile on my face. They sound ok, good at times, but with a very small "wow" factor. Everything is predictable, it's either an acoustical song or a poprock song. You don't seem to have "your sound". Try to work on that, and try writing stuff that's a bit more off the main road.
One last thing:
I know it's a praise album, but absolutally every song seems to have the exact same theme and idea. That could be the entire point, but it doesn't keep me interested for 10 songs.
Hope that helps
