God can only be known by means of a supernatural revelation of Himself Apart from the Scriptures, even a theoretical acquaintance with Him is impossible. It still holds true that ‘the world by wisdom knew not God’ (1 Corinthians 1:21).
Where the Scriptures are ignored, God is “the unknown God” (Acts 17:23).
But something more than the Scriptures is required before the soul can know God, know Him in a real, personal, vital way. This seems to be recognized by few today. The prevailing practice assumes that a knowledge of God can be obtained through studying the Word, in the same way as a knowledge of chemistry may be secured by mastering its textbooks. An intellectual knowledge of God maybe; not so a spiritual one.
A supernatural God can only be known supernatural (i.e. known in a manner above that which mere nature can acquire), by a supernatural revelation of Himself to the heart. ‘God, who commanded the light to shine out of darkness, hath shined in our hearts, to give the light of the knowledge of the glory of God in the face of Jesus Christ’ (2 Corinthians 4:6).
The one who has been favored with this supernatural experience has learned that only ‘in thy light shall we see light’ (Psalm 36:9).
