"And the Lord will create upon every dwelling place of mount Zion, and upon her assemblies, a cloud and smoke by day, and the shining of a flaming fire by night." Isaiah 4:5
There is an allusion here to the cloudy pillar which rested upon the tabernacle. It was as a cloud by day, but as a pillar of fire by night. The reason of this is evident. By day, the cloud and the smoke were sufficiently visible; but not so in the night season. In the night, therefore, it was a pillar of fire, that the presence of the Lord might be distinctly seen. Spiritually viewed, this night may signify dark seasons in the soul; for there is night as well as day in the experience of God's saints. Now when they are in these dark seasons, they need clearer and brighter manifestations of the Lord's presence than when they are walking in the light of day. Thus this "shining of a flaming fire by night" may represent the shining in of the Lord's clearer, fuller, and more manifested presence, the livelier and more powerful application of his word to the heart; the brighter evidences and clearer marks that he gives of his favor, which, compared with the cloud, are as the shining of a flaming fire. It is the same presence of God, and the same glory, as was the case with the cloudy pillar; but that presence and that glory are seen in a more conspicuous manner as giving light in seasons of darkness.
The shining of a flaming fire by night may also represent the shining light of the word of truth which is spoken of as "a light that shines in a dark place" (2 Peter 1:19). How often when the mind is dark, and evidences obscured, there is little else seen but the clear shining of the word of truth to which the soul turns its eyes as its only guiding light. "Your word," says David, "is a lamp unto my feet, and a light unto my path." We often get into spots where we have to look outside of ourselves to the clear shining of truth in the word of God; for there is darkness everywhere else; and to that light we have to look and wait, and sometimes at a great distance and for a long season, until that word comes near and begins to shine into the heart.
But with that shining light, as it draws near and gives forth its comforting rays and beams, comes in due time the presence and glory of God. So to fix our heart upon the word of promise, and wait for its fulfillment, is to walk by faith and not by sight. Thus to Abraham the word of promise was by day a cloud; but when "a horror of great darkness fell upon him," the same word of promise, as the word of a covenant God, was as a burning lamp that passed between the pieces of the offered sacrifices (Gen. 15:17).
