Sermon in a symphony?

I want to address a common theme of atheistic thinking about God as shown in recent comments, that only measurable experimental evidence would persuade of His existence. It's my conviction that such a demand is a feature of a western scientific materialist mindset, and that as an approach to the question of God it is fundamentally flawed. Coming from an arts not science background, I find image, metaphor and analogy helpful ways to think, opening up fresh perspectives. Picking up on the tail end of comments from the 'All channels engaged?' post below, I'm pondering the metaphor of a symphony or other great work of art. Listening to great music, one is intuitively aware of intelligent, inspired creative activity underlying the experience, and the work itself. It's a big picture kind of response, a response of the whole person. But it's not the only way of contemplating music; changing the focus, you could study in detail the quantity, range and patterns of notes, and their effect at various levels: on the ear drum, on the brain, on the emotions. In other words, the musical experience can be broken down, reduced and explained in many ways. But most reasonable folk would accept that no amount of such analysis alters the experienced reality of a great work of art, stimulating the senses, stirring the emotions - and plainly the product of genius. And note, that power and mystique is not something 'extra' to the analysable musical notes and effects; it's right there in it. It's a case of different ways of appreciating the phenomena. I see a parallel with nature and God. The biblical perspective is clear, that nature manifests the presence and glory of God, Romans 1:19,20. In the western scientific community in particular, this perspective has in large part been lost. And it strikes me that looking for 'the difference God makes' as an additional factor in the processes, through measurable controlled experiment, is like a musical analyst searching for 'evidence of genius' by analysing the notes of a symphony. It doesn't work like that. You need to widen the camera angle and open up the avenues of appreciation. Problem is, prevailing scientific ideology can make that difficult to do. Which takes us to the heart of the problem: the problem of the heart. Jesus said spiritual 'new birth' is needed to enable us to see spiritual realities - like a chrysalis opening its wings to absorb and enjoy the light and warmth of the sun. A beautiful process - for which faith is a vital ingredient.
