"He that dwelleth in the secret place of the most High shall abide under the shadow of the Almighty" (Psalm 91:1)
It is important that we get still to wait on God. And it is best that we get alone, preferably with our Bible outspread before us. Then if we will we may draw near to God and begin to hear Him speak to us in our hearts.
I think for the average person the progression will be something like this: First a sound as of a Presence walking in the garden. Then a voice, more intelligible, but still far from clear.
Then the happy moment when the Spirit begins to illuminate the Scriptures, and that which had been only a sound, or at best a voice, now becomes an intelligible word, warm, and intimate and clear as the word of a dear friend.
Then will come life and light, and best of all, ability to see and rest in and embrace Jesus Christ as Saviour and Lord and All.
O God and Father, I repent of my sinful preoccupation with visible things. The world has been too much with me. Thou hast been here and I knew it not. I have been blind to Thy presence. Open my eyes that I may behold Thee in and around me. For Christ's sake, Amen.
