So then, just as you received Christ Jesus as Lord, continue to live your lives in him, rooted and built up in him, strengthened in the faith as you were taught, and overflowing with thankfulness.
See to it that no one takes you captive through hollow and deceptive philosophy, which depends on human tradition and the elemental spiritual forces of this world rather than on Christ.
For in Christ all the fullness of the Deity lives in bodily form, and in Christ you have been brought to fullness. He is the head over every power and authority.
And the gospel has always, as its natural effect, evangelism, reaching the lost, but not so those who are carriers of heresy. They want to be parasites. They want to live off the church. They want to bring to the church some new revelation. "Our ministry is not really to the lost; our ministry is to the church. Our truth that we have to share, it's for the church." And so he points them back to the beginning, as you've received Christ Jesus so walk ye in Him. Don't get carried off with some of these new revelations that God has just unveiled in these last days. Actually, we don't need any new revelations of truth. What we do need is new experiences in the established truth. God has given to us all that we need for the life of godliness in His word; it's all there. We don't need any new revelations. But what we do need is fresh experiences in the old truths of God's word. So beware, lest any man would beguile you with enticing words. For as you've received Christ, so walk ye in Him. Rooted and built up in Him. Christ is the base, the foundation. But He is also the One on whom we build. Our lives are to be centered in Jesus Christ.
