because the song says so
I don't have a problem at all when someone refers to the Bible, you know, God's holy word, and claims that we should act upon the words that are written in scripture. In fact I think that it is great! Especially in a worship setting! For instance, if during a worship service this was read it could only better the worship experience, for me at least. Psalm 30:4 - "Sing to the LORD, you saints of his; praise his holy name."
However, I find it odd that we are charged at times to do things because thats what the song says. The song says "we lift our hands," "I rejoice," or "You deserve the glory," and now you are asking me to do this because the song says to. Hmmm. And yet when asked to apply that to my life I find myself thinking are you and idiot? Even when it does agree with scripture, NEVER NEVER NEVER ask me do something because thats what the song says. Charge me with scripture (in context please) but NEVER because this song says.
