King David acknowledges in beautiful poetry that he is known by God. He is known, surrounded, and created by God Himself. The Lord knows His people intimately and thoroughly. He knows when they come and when they go, when they sit and when they rise. He knows their inward and outward lives. He also surrounds His people. In other words, there is nowhere to hide, nowhere to run from this all-knowing God. The Lord knows His people so intimately because it was he who made each one of them, fashioning them in their mother's womb. And David's response is to cry out for God to know Him, to search Him out, to judge Him. This Psalm foreshadows when Another would come who was known intimately by God, yet forsaken on a cross, to be crushed, in order to win the lives of many. It is through this sacrifice that we can know this all-knowing God with the same intimacy with which He knows us.
