Colossians 2:1-8

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. [For my hope is] that their hearts may be encouraged as they are knit together in [unselfish] love, so that they may have all the riches that come from the full assurance of understanding [the joy of salvation], resulting in a true [and more intimate] knowledge of the mystery of God, that is, Christ, 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]. Therefore as you have received Christ Jesus the Lord, walk in [union with] Him [reflecting His character in the things you do and say—living lives that lead others away from sin], having been deeply rooted [in Him] and now being continually built up in Him and [becoming increasingly more] established in your faith, just as you were taught, and overflowing in it with gratitude. See to it that no one takes you captive through philosophy and empty deception [pseudo-intellectual babble], according to the tradition [and musings] of mere men, following the elementary principles of this world, rather than following [the truth—the teachings of] Christ.
