Colossians 2:1-3 NKJV

[1] For I want you to know what a great conflict I have for you and those in Laodicea, and for as many as have not seen my face in the flesh, [2] that their hearts may be encouraged, being knit together in love, and attaining to all riches of the full assurance of understanding, to the knowledge of the mystery of God, both of the Father and of Christ, [3] in whom are hidden all the treasures of wisdom and knowledge.
