"The eyes of the Lord are in every place, beholding the evil and the good" (Proverbs 15:3)
The omnipresence of the Lord is one thing, and is a solemn fact necessary to His perfection.
The manifest Presence is another thing altogether, and from that Presence we have fled, like Adam, to hide among the trees of the garden, or like Peter, to shrink away crying, "Depart from me; for I am a sinful man, O Lord" (Luke 5:8).
So the life of man upon the earth is a life away from the Presence, wrenched loose from that "blissful center" which is our right and proper dwelling place, our first estate which we kept not, the loss of which is the cause of our unceasing restlessness.
The Holy Spirit is God, and the most important thing is that the Holy Spirit is present now. There is unseen deity present. I cannot bring Him to you; I can only tell you that He is here.
