Colossians 2:1–3 (ESV)
[1] For I want you to know how great a struggle I have for you and for those at Laodicea and for all who have not seen me face to face, [2] that their hearts may be encouraged, being knit together in love, to reach all the riches of full assurance of understanding and the knowledge of God’s mystery, which is Christ, [3] in whom are hidden all the treasures of wisdom and knowledge.
