It is not always easy to recognize what is merely a matter of personal taste – and capable, therefore, of being changed – and what is fundamental to worship and should, therefore, be unaltered. We should encourage people to test every contribution by its God-centeredness and its ability to edify, and for all to learn to see debatable issues from other people’s point of view… The most vital truth we must convey is that what is important is not how acceptable our worship is to ourselves or to others, but how acceptable it is to God – a priority sometimes forgotten (Derek Prime and Alistair Begg).
