“For I want you to know what a great conflict [struggle] I have for you and those in Laodicea, and for as many as have not seen my face in the flesh, 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, in whom are hidden all the treasures of wisdom and knowledge. Now this I say lest anyone should deceive you with persuasive words.” Colossians 2:1-4.
“And He is the head of the body, the church, who is the beginning, the firstborn from the dead, that in all things He may have the preeminence. For it pleased the Father that in Him all the fullness should dwell, and by Him [Jesus] to reconcile all things to Himself [God the Father], by Him [Jesus], whether things on earth or things in heaven, having made peace through the blood of His cross.” Colossians 1:18-20.
“For this reason we also, since the day we heard it, do not cease to pray for you, and to ask that you may be filled with the knowledge of His will in all wisdom and spiritual understanding…” Colossians 1:9.
