Tesco Delivery Man or Minister?

One of the great mainland innovations some years ago was Tesco's offering of online shopping and a delivery van service. It is just great, you order up what you want, pay for it and then someone else goes and gets it and delivers it. Brilliant! In an age of consumerism and self selection it's just perfect.
However, being a minister in this age of consumerism has its problems, because when I deliver the Sunday Service I am sure a number of folk are thinking 'that's not what I ordered'. Some leave the church and say that they 'did not know the hymns', or 'they did not like the hymns'. or 'there were a lot of Graham Kendrick songs today'.
Having attended a Ministry Conference recently, and heard stories of my colleagues expeiences in ministry, it seems to me quite common for folk to think that Presbytery must have delivered the wrong man or woman. Just as they would with Tesco's, they grumble and complain to ane another about the bad service... and occasionally someone may complain to Presbytery. It is consumerism at work.
As a minister my real sadness abou this is that many seem to attend sunday services for what they can get, rather than what they can give. It is after all Sunday 'Worship', where Christians are supposed to gather before a 'worthy' God and sing his praises. It is written that 'God inhabits the praises of his people' and that is so true. As Christians learn how to praise God they learn about the joy and freedom that God alone can bring to our lives.
I enjoy being a minister, since it is such a privilige, but being a delivery man is not a pleasant task since one meets unpleasant customers from time to time. So please pray for the consumers in congregations everywhere... pray that they might come to know the joy of giving themselves to a worthy God and Saviour.
Thank God too for those folk that know that sense of joy and fullness when gathering to worship God. To see their smiles and sometimes their tears of release is just great. It seems to me that they are able to enjoy the full range of opportunities to worship and enjoy learning new songs. In this sense they cannot be described as being 'meat and two veg' people. Indeed the length and breadth of opportunity in the Christian life is staggering because we have a great God.
