There's nothing wrong with making music, for sure, but it's very important to be clear about what worship is, and what it isn't. A lot of things that Christians call "worship" are not in fact worship at all. Often emotion is confused with worship, and music is a very emotive thing.
I read an article recently which really drove home that point:
http://www.spectator.co.uk/life/low...hing-like-an-hour-of-rollicking-hymn-singing/
This article was written by Jeremy Clarke, a journalist who writes a column called 'Low Life' in
The Spectator magazine. Mainly, the column describes episodes from his life, many of which eminently bear out the title of the column. To put it mildly, he doesn't show any signs of being a believer. In this article, he writes:
"We then rose again to sing ‘How Great Thou Art’. After the gentle warm-up of ‘Christ Triumphant’, we really let go with this one. I know the words by heart. They melt it every time I sing it. It’s that soaring chorus: ‘Then sings my soul, my Saviour God to Thee’. It trips me up every time. Once again the old feeling of helplessness engendered by those words and that melody stole over me and I lifted my face and sang out hardly knowing where I was."
This is pure emotion, and there isn't an iota of worship in it. Yet Mr Clarke, and many church-going unbelievers like him, will believe that they're having a 'religious experience'. Some may even believe that it will contribute to their eternal salvation. That is the subtle danger of music, made all the worse by the decadent and elaborate way that it's presented in many churches.
Now, I wouldn't suggest for a moment that we shouldn't sing hymns and spiritual songs - the scripture enjoins us to do just that. I would just caution against calling music, the melody in itself, worship. So much is called worship which in reality is anything but. The threatrics of the Roman Catholic Mass are a prime example - and if there is any worship rising out of those occasions, it'll be in spite of the histrionics of the religious play, not because of them.
Worship is in spirit, produced by the work of God and the service of the Holy Spirit, and nothing outward of the works of a man's hands can enhance or contribute to it. It is purely of God, from Himself and to Himself - otherwise, He couldn't take full pleasure in it. Are we reconciled to God by the works of our hands? Surely not. Christ has done it all. So, having been brought into the presence of God entirely through the movements of divine love, grace and mercy, are we going to go back for the works of our hands which were of no avail whatsoever when we were lost sinners, and use them to praise our Saviour God? Is what God set aside when Christ came in to be brought back again? Thankfully not, because Christ is all-in-all. To suggest that we can add anything to the work of the Lord Jesus - whether in salvation or in priestly service - would be totally inconsistent with the truth.
