This booklet is based on five letters answering questions about Christian singing that appeared in the Bible Treasury magazine. We republish them because they explain the purpose and character of Christian singing very clearly. To sing to God in a scriptural way glorifies Him, and encourages and edifies us as we do it. Though these letters were written in the 1890s, they are as relevant now as they were then. They are well worth reading because of the spiritual substance they contain and the practical instruction they give. At the same time, the author's straightforward style of writing means they are accessible to the reader in English. May this booklet stimulate us to sing as we should even in difficult days when we might be tempted to keep silent.
