As you have therefore received Christ, [even] Jesus the Lord, [so] walk (regulate your lives and conduct yourselves) in union with and conformity to Him. Have the roots [of your being] firmly and deeply planted [in Him, fixed and founded in Him], being continually built up in Him, becoming increasingly more confirmed and established in the faith, just as you were taught, and abounding and overflowing in it with thanksgiving. See to it that no one carries you off as spoil or makes you yourselves captive by his so-called philosophy and intellectualism and vain deceit (idle fancies and plain nonsense), following human tradition (men's ideas of the material rather than the spiritual world), just crude notions following the rudimentary and elemental teachings of the universe and disregarding [the teachings of] Christ (the Messiah).
My counsel for you is simple and straightforward: Just go ahead with what you've been given. You received Christ Jesus, the Master; now live him. You're deeply rooted in him. You're well constructed upon him. You know your way around the faith. Now do what you've been taught. School's out; quit studying the subject and start living it! And let your living spill over into thanksgiving.
Watch out for people who try to dazzle you with big words and intellectual double-talk. They want to drag you off into endless arguments that never amount to anything. They spread their ideas through the empty traditions of human beings and the empty superstitions of spirit beings. But that's not the way of Christ. Everything of God gets expressed in him, so you can see and hear him clearly. You don't need a telescope, a microscope, or a horoscope to realize the fullness of Christ, and the emptiness of the universe without him. When you come to him, that fullness comes together for you, too. His power extends over everything.
