Colossians 2:1-8 NKJV
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, 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. For though I am absent in the flesh, yet I am with you in spirit, rejoicing to see your good order and the steadfastness of your faith in Christ.
As you therefore have received Christ Jesus the Lord, so walk in Him, rooted and built up in Him and established in the faith, as you have been taught, abounding in it with thanksgiving.
Beware lest anyone cheat you through philosophy and empty deceit, according to the tradition of men, according to the basic principles of the world, and not according to Christ.
NKJV: New King James Version
