“Holy, holy, holy! 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, in love, and purity.”- Reginald Heber, “Holy, Holy, Holy,” third verse
We cannot grasp the depths of God’s holiness and yet we can trust him.
