“In our English hymnal there are twenty to thirty hymns concerning Christ as the Spirit. In the compilation of the hymnal, we did our best to collect all the truths expressed in hymns from different Christian backgrounds. Therefore, our hymnal may be considered a collection of the hymns of theology. If you want to study real theology, you need to first study our hymnal.”
