Charles H. Spurgeon on Psalms 139:8

If I ascend up into heaven, thou art there. Filling the loftiest region with his yet loftier presence, Jehovah is in the heavenly place, at home, upon his throne. The ascent, if it were possible, would be unavailing for purposes of escape; it would, in fact, be a flying into the centre of the fire to avoid the heat. There would he be immediately confronted by the terrible personality of God. Note the abrupt words —"THOU, THERE." If I make my bed in hell, behold, thou art there. Descending into the lowest imaginable depths among the dead, there should we find the Lord. THOU! says the Psalmist, as if he felt that God was the one great Existence in all places. Whatever Hades may be, or whoever may be there, one thing is certain, Thou, O Jehovah, art there. Two regions, the one of glory and the other of darkness, are set in contrast, and this one fact is asserted of both —"thou art there." Whether we rise up or lie down, take our wing or make our bed, we shall find God near us. A "behold" is added to the second clause, since it seems more a wonder to meet with God in hell than in heaven, in Hades than in Paradise. Of course the presence of God produces very different effects in these places, but it is unquestionably in each; the bliss of one, the terror of the other. What an awful thought, that some men seem resolved to take up their night's abode in hell, a night which shall know no morning.
