God, The Holy Spirit (Ghost) is the examiner for the Christian. He weighs every aspect of our lives. He looks into our lives methodically in order to discover our condition, investigate our motives and actions, and to determine our state of qualification. He makes a thorough, accurate, exacting, and complete investigation; omitting nothing. "For man looketh on the outward appearance, but the Lord looketh on the heart" (1 Samuel 16:7).
