Although a special hymn for Trinity Sunday, it is sometimes appointed as a morning hymn, as in the Society for Promoting Christian Knowledge Church Hymns, 1871.
It peaked at number two in New Zealand and received a Platinum certification.
Though the darkness hide Thee, Though the eye of sinful man Thy glory may not see; Only Thou art holy; there is none beside Thee, Perfect in power, love, and purity.
Of course, the flesh is weak Mark 14:38.
