“Therefore, as you received Christ Jesus the Lord, so walk in him, rooted and built up in him and established in the faith” (v6-7). Just decades after Jesus lived among them, Paul warned believers against false teachers who offered a mix of human tradition, “empty deceit,” and the “elemental spirits of the world” rather than the gospel (v8). Paul reminded believers that in Jesus, “the whole fullness of deity dwells bodily” (v9); in other words, Jesus is fully God and more than enough for our salvation.
“You have been filled in him” (v10). All the spiritual “extras” (visions, angelic prophecies, or human traditions) pale in comparison to the fact that the resurrected Jesus lives in us by His Spirit.
