One might be tempted to think that these terms imply but trivial distinctions, did the Apostle not
make specific use of them in Eph. 5:19 and Col. 3:16. We may thus be sure that in their use the
Spirit of God has something special to unfold for our profit. A psalm is not necessarily a psalm
of David. The thought of God’s mercy was the prominent impulse which inspired the Psalmists
to pen the psalms. So, too, it is the deep sense of the mercy of God in our souls which will lead
us to burst forth in a psalm to gladden thei heart of the Lord, e.g.,

"Our Shepherd is the Lord, . . ." (L.F. 238).

Hymns have reference to the greatness and majesty of our blessed Lord calling forth our audible
praise. This is not shutting out the fact that unless we are stirred in our souls we shall not be able
to give expression rightly to a hymn. But that does not give essential character to the hymn.
Everything sinks into insignificance in the presence of the greatness of the Lord, e.g.,

"Jesus, Thou alone art worthy . . ." (L.F. 82).

Spiritual songs on the other hand, refer more to the greatness of the Spirit of God within leading
us not only to make melody in our hearts to the Lord but to break forth into singing. The gladness
in our hearts is called up in response to the joy of His heart. What stirring impulse can prompt
such words as:_

"Praise ye the Lord again, again . . ." (L.F. 156).
