Praise sung to God is the effect of a saving knowledge, given by the Holy Spirit through Scripture. On that all Christians are agreed, but on the words to be used in praise there is considerable difference, and even controversy. The question is heard, "Why not return to the one inspired book of praise which God has given in the Psalms? Should anything be allowed to replace inspired Scripture?" This author argues that there are biblical reasons why it is a mistake to suppose that the words of the Old Testament alone are to be used in the singing of praise.
