I guess the question is does it matter to God if I use something that is messed up in regards to His commandments and teachings in my worship to Him? Or, is God only interested in my heart while I am worshipping Him?
When you put the question that way it almost seems silly to ask it. God IS concerned about my heart when I worship Him. Jesus told us through the gospel of Matthew that we have to come to Him without resentment in our heart
"Therefore, if you are offering your gift at the altar and there remember
that your brother has something against you, leave your gift there in front of the altar. First go and be reconciled to your brother; then come and offer your gift." Matthew 5:23,24
However, he also said in John 4:24 "God is spirit, and his worshipers must worship in spirit and in truth." So now I wonder since He wants me to worship Him with my spirit and to come to him in truth then does that mean that if I know I use something that was originally conceived in error can I use it to worship Him?
This debate in my mind came while I was listening to one of my favorite CD's - "Exodus" by Bob Marley and the Wailers. Much of his music speaks of God, Jesus, Zion, and "Jah". I just started listening to the words a bit closer and I thought...wow this makes sense! So I did a bit of research and it turns out that "Zion" is not the Zion I know of and that "Jah" is not a different name for Jehovah. (if you want to find out about what they mean look up "Rastafari Movement")
But if I speak these words and use them to refer to my God and for His glory does it diminish my worship to Him (even though I know where they came from)? If the earthly "audience" doesn't know that they were originally used in error does it matter?
I don't know.
P.S. Now I'm even more confused, since the Christian group Acappella did a song some years ago called "Talk to Jah" and grouped that name in with Jehovah. Yep, color me confused...
