This version of Book I of Worship Jesus in Song is for the worshippers or congregation in a church, and as a simple, compact version of the book for guitarists or anyone else who uses chords to play the songs. Many of these songs are settings of passages from the Bible. Some of them are rounds, most of the songs will be easily singable by anyone, a few of them are complicated and only a worship team or choir that practices regularly will be able to sing them. (For more detailed instructions, refer to introduction in the Choir and Accompaniment book, or the SA(A) book.) There are sad songs as well as happy ones. In fact, the Bible contains many sad psalms, laments, and passages expressing grief as well as consolation, and Christian worship ought to acknowledge the full range of human emotions: while joy is the predominant note in the New Testament, even Paul acknowledges that the Christian life is not always a 'bed of roses' in 2 Corinthians 1:8, "We do not want you to be uninformed, brothers and sisters, about the troubles we experienced in the province of Asia. We were under great pressure, far beyond our ability to endure, so that we despaired of life itself." But every sad psalm in the Bible also contains some element of comfort, so also with these. But the predominant note is joy and thankfulness, in the hope all share who believe in the resurrection of Jesus Christ, and our own future resurrection when the new heavens and the new earth come to be.
