There is such a thing as proper worship. No matter how well intended and honest and pure we think our worship is, if we do not accurately know God, there will be trouble when trying to worship God properly. In the end, the question we need to ask ourselves is, who defines it?
Yes, music can move us. Music can bring us together. Music can change us. Music is so powerful. I love music. But for us as Christians, our hearts must always go beyond the music.
The only hope that does not disappoint, that does not fail, is the hope we have in Christ. In what He has done.
