Let me set a scene (and weirdly, I see this happening in an Irish accent):
"That was a great service" Joe said ... meaning good contemporary music (for a bunch of amateurs), with 1/3rd of the congregation singing well, another 1/3rd mumbling their way through the words, and 1/3rd stoically waiting for it all to end.
It almost makes me cry sometimes.
So now it's after the service and we have Jesus sitting down for pint of Guinness with Joe. After all, Jesus is with us all the time, and I presume he'd drink Guinness, so why not?
"So Joe, I notice you were rather reserved in the service. I didn't quite catch your voice during the singing"
"uh .. .yeah, I guess so."
"Why is that now? I mean, I know why, because I know you inside-out after all. That omniscient thing and so forth. But you tell me how you see it, because I'm not sure you know yourself."
"Well ... I guess I'm a little embarrassed singing out loud like that. I'm not a really into this extrovert stuff. And, I mean, the words are not quite what one would normally say in front of others ... that sort of language is personal-like, something for me alone."
"Of course ... I ... ummmm ..."
"Ok, I know, remember the omniscient thing? Moving on ... or back as it may be: Worship. Tell me, what do you think of me? I really want to know."
"You know what I think of you Jesus, you're omniscient."
"Ah, now you sound like all those husbands whose wives complain that they never say 'I love you'. It also reminds me of that fish breakfast I had with Peter ... he also tried that angle on me."
"Oh go look it up another time. Joe, let me tell you a little secret. I don't want you to tell me what you think for my benefit, I want you to do it for YOU, and for those around you. I'm the omnipotent and all that, I don't NEED anything, I'm the word that was before and will always be, I'm humble!"
"Humble! I'm everything and I'm humble. Because being humble means being no more than you are, and no less than you are. Since I AM, no more and no less, I am humble. But you? Where's your humility?"
"Oh good grief, is that the extent of your vocabulary? When you keep quiet in singing worship, you're saying I'm not worth the effort. When you don't acknowledge me with all your mind, body, soul, and strength, you're effectively claiming for yourself something of me. You're saying to me that you're more than I know you to be. You're trying to get an edge over ME. You're trying to say you're in charge. That I am not all important. That's not humble. That's stupid."
"But, but ... what's so special about making a fool of myself while singing songs? It's not like it's a big event. Only lasts twenty minutes or so, and anyway, it's Sunday morning and I'm tired, and nobody notices what I'm doing"
"Hmm, so birth lasts a few hours, getting married takes even less, and sex only lasts a short while if you're lucky. Even death is a matter of seconds! Does that make them unimportant? Don't you tell me about the value of time, I made time, I walk through time, time is not what's important. And by the way, people ARE affected by what you do! If you don't worship, your neighbour shrinks back too, so you're hurting them. It's only the one's deeply in love with me who actually keep the true church worship going."
"Why are you getting so steamed up about this?"
"Because it damages YOU, you twit. Don't you see, every time you pass on an opportunity to EXPRESS worship, you lose an opportunity to be who you were made to be. And every time you choose to not express yourself, you choose to hide a reality from yourself and from others. You hold back others! Anyway, making a fool of yourself is not something you'd have to put much effort into.
Listen: there's two ways to approach worship. One way is to start with what you know in your heart to be real -- draw on those all-too-rare moments when your eyes were really open and you experienced me being right there. And from there you tell your mind to get it's act into gear and choose to put some thoughtful expression to the heart's feelings. Music is great for that, it adds a rich meaning of words. The other option is to start in the mind; take what you KNOW is the Truth, not what you'd like to be the truth. Then tell your heart to stop being so afraid of emotion and get with it. Music's great, because it catches the heart in a net of melody and merges it with your mind. It doesn't matter where you start. It only matters where you end ... in expression! Stop short of that and you may as well have never begun.
Forget about what others think of you. It's me, the omnipotent one and all that, who is standing right there in your face. Get it?"
