The earth is the LORD's, and the fullness thereof; the world, and they that dwell therein. For he hath founded it upon the seas, and established it upon the floods.
Who shall ascend into the hill of the LORD? or who shall stand in his holy place?
That their hearts might be comforted, being knit together in love, and unto all riches of the full assurance of understanding, to the acknowledgment of the mystery of God, and of the Father, and of Christ;
In whom are hid all the treasures of wisdom and knowledge.
Definition of the word MYSTERY:
"Something hidden from human knowledge and fitted to inspire a sense of awe; especially something incomprehensible through being above human intelligence. An enigma; anything artfully made difficult."
God is good, even when life is hard, even when he chooses to be mysterious or maybe more so because of it.
