Well, I've been listening to Voddie Baucham again, this time about worship. While I do not agree 100% with what he says, I agree with a great deal about it. What I've been able to apply to my life is this definition of authentic worship. (not necessarily just music)
Authentic worship happens when I place my mind's attention and my heart's affection on God, praising Him for who He is and for what He has done.
I find this helpful because even if you have good, godly music, and I think you can and you should,
you must put your heart and mind into its . It can be singing, praying, giving, listening to a sermon, witnessing to others. That's all worship.
