Does not one have to be in the right mood for singing, either to engage in it personally or to enjoy that of others? Such is the idea which prevails generally among professing Christians. From one standpoint, it is of course true but from another, it is not so. But surely no one sings when he is thoroughly miserable, unless he forces himself to do so.
Ah, is not that exactly what the worldling would say? It is! and, sad to say, the great majority of church members hold the same view, which only evidences the carnality of their conceptions. Are the children of God in no better case than the children of the devil? Are they too "creatures of circumstances," swayed by the situation in which they find themselves, a prey to their feelings?
But must not one be in a cheerful frame in order to really sing?
Yes, to sing naturally. But does not the saint require to be on the mount, before he can break forth into spiritual song? Such questions indicate how unscriptural the thoughts of most people on this subject are: they reduce singing to a mere physical exercise, an outburst of their natural emotions. Christians are bidden to delight themselves in the LORD (Psalm 37:4); and if they really do so, songs of praise are bound to spring up in their hearts. That it is not God's will that His children should be miserable, is clear from the fact that the service of song is an ordinance of worship; both under the old covenant and the new. (1Chronicles 6:31, Ephesians 5:19)
Singing is an act by which the soul renders homage, and the heart adores the glorious One
