Colossians 2:1, 3-5

For I want you to know how great a struggle I have for you and for those [believers] at Laodicea, and for all who [like yourselves] have never seen me face to face.

in whom are hidden all the treasures of wisdom and knowledge [regarding the word and purposes of God]. I say this so that no one will deceive you with persuasive [but thoroughly deceptive] arguments. For even though I am absent [from you] in body, nevertheless I am with you in spirit, delighted to see your good discipline [as you stand shoulder to shoulder and form a solid front] and to see the stability of your faith in Christ [your steadfast reliance on Him and your unwavering confidence in His power, wisdom, and goodness].
