Colossians 2:6-8

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).
