Charles H. Spurgeon on Psalms 139:18

If I should count them, they are more in number than the sand. This figure shows the thoughts of God to be altogether innumerable; for nothing can surpass in number the grains of sand which belt the main ocean and all the minor seas. The task of counting God's thoughts of love would be a never ending one. If we should attempt the reckoning we must necessarily fail, for the infinite falls not within the line of our feeble intellect. Even could we count the sands on the seashore, we should not then be able to number God's thoughts, for they are "more in number than the sand." This is not the hyperbole of poetry, but the solid fact of inspired statement: God thinks upon us infinitely: there is a limit to the act of creation, but not to the might of divine love. When I awake, I am still with thee. Thy thoughts of love are so many that my mind never gets away from them, they surround me at all hours. I go to my bed, and God is my last thought; and when I wake I find my mind still hovering about his palace gates; God is ever with me, and I am ever with him. This is life indeed. If during sleep my mind wanders away into dreams, yet it only wanders upon holy ground, and the moment I wake my heart is back with its Lord. The Psalmist does not say, "When I awake, I return to thee", but, "I am still with thee"; as if his meditations were continuous, and his communion unbroken. Soon we shall lie down to sleep for the last time: God grant that when the trumpet of the archangel shall waken us we may find ourselves still with him.
