A dossier can hold a person’s name, history, habits and photographs and still miss the person. A mirror shows a face and still misses the man. “For what man knoweth the things of a man, save the spirit of man which is in him?” (1 Corinthians 2:11).
What a person is made of
God made all of it, and He means to keep all of it: “I pray God your whole spirit and soul and body be preserved blameless unto the coming of our Lord Jesus Christ” (1 Thessalonians 5:23).
Others cannot know us
People see the cover. “Man looketh on the outward appearance, but the LORD looketh on the heart” (1 Samuel 16:7). We fall in love with what we see and what we hope a person is, without ever knowing the whole person.
Not knowing others is what made me afraid to pick out a wife. I would have gone by sight alone. So I prayed, “God, don’t let me marry the wrong one.”
We cannot fully know ourselves
That is what shocks us in a pinch. Peter said, “Though I should die with thee, yet will I not deny thee” (Matthew 26:35), and the pressure showed him a Peter he had never met. “The heart is deceitful above all things, and desperately wicked: who can know it?” (Jeremiah 17:9). “Who can understand his errors? cleanse thou me from secret faults” (Psalm 19:12).
God knows the whole person
Psalm 139:1
He sees what no dossier records and what we cannot see in ourselves, and He still calls us.
He gives His Spirit so we can see
When His Spirit comes in, the candle is lit. “Now we have received… the spirit which is of God; that we might know” (1 Corinthians 2:12). He does not only show us the heart; He changes it: “A new heart also will I give you, and a new spirit will I put within you” (Ezekiel 36:26). It begins the way Peter preached it: “Repent, and be baptized every one of you in the name of Jesus Christ for the remission of sins, and ye shall receive the gift of the Holy Ghost” (Acts 2:38).
One day, fully
“For now we see through a glass, darkly; but then face to face: now I know in part; but then shall I know even as also I am known” (1 Corinthians 13:12).
This study captures something of what can never truly be captured of a person in this life. Until then, the prayer is David’s: “Search me, O God, and know my heart: try me, and know my thoughts” (Psalm 139:23).
