Sometimes our hearts are strangely stubborn and will not soften or grow tender no matter how much praying we do. At such times, it is often found that the reading or singing of a good hymn will melt the ice jam and start the inward affections flowing. That is one of the uses of the hymnbook. Human emotions are curious and difficult to arouse, and there is always a danger that they may be aroused by the wrong means and for the wrong reasons. The human heart is like an orchestra, and it is important that when the soul starts to sound its melodies, a David or a Bernard or a Watts or a Wesley should be on the podium. Constant devotion to the hymnbook will guarantee this happy event and will, conversely protect the heart from being led by evil conductors.
Every Christian should have lying beside his Bible a copy of some standard hymn book. He should read out of one and sing out of the other, and he will be surprised and delighted to discover how much they are alike. Gifted Christian poets have in many of our great hymns set truth to music. Isaac Watts and Charles Wesley (possibly above all others) were able to marry the harp of David to the Epistles of Paul and to give us singing doctrine, ecstatic theology that delights while it enlightens.
