This study seeks to show that a carefully planned, solemn service with the inclusion of classical texts and with several recurring elements in addition to the sermon, as it has been practiced by the majority of the church for almost two thousand years, does not represent spiritual rigidity. Rather, it is in harmony with biblical revelation and is a great spiritual help. To show this, we will discuss in detail which elements, based on biblical testimony, are indispensable to regular worship. The goal here is not to urge Christians to change churches or to impose a completely different worship service on congregations. I believe that many elements of this book can be incorporated into any worship tradition, and the book contains many suggestions for all Christians, regardless of whether they are used to a much ‘freer’ or a much more ‘liturgical’ worship service than I propose in this book.
