Let us just remind ourselves that surely the purpose of the biblical revelation of God’s holiness is to teach us how to approach Him. It is not mere theoretical knowledge that we are asked to try to grasp with our understandings. Its purpose is very practical. In the words of the author of the epistle to the Hebrews, we are to approach God ‘with reverence and godly fear’ (Heb. 12:28). He is always to be approached in that way, wherever you are; when you are alone in a room, or when you are meeting as a family to pray, or when you are in a public service, God is always God and He is always to be approached ‘with reverence and godly fear’. No such expression as ‘Dear God’, for example, is to be found in the Scriptures.*
Soli Deo Gloria!
For His Glory,
