Rooted in Christ – 2:6-8
6 So then, just as you received Christ Jesus as Lord, continue to live your lives in him, 7 rooted and built up in him, strengthened in the faith as you were taught, and overflowing with thankfulness.
8 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.
These three verses offer, first, an encouragement to continue to live faithfully for Christ, and second, a warning against being taken in by false teaching. It is never enough that someone simply “prayer the prayer of salvation” and then go on about their business as though nothing significant had actually happened. Embracing Christ is a cosmic event with eternal ramifications. It is not simply a one-time transaction, but rather the beginning of an eternal relationship with one’s Creator and Redeemer.
Embracing Christ is a cosmic event with eternal ramifications.
Paul is fond of using variations of the phrase “in Christ.” To be in Christ means to be intimately connected to Christ. The larger idea is familial. To be in Christ means to be a member of his family. No doubt this phrase, for Paul at least, carries with it intonations of God’s covenant with Abraham. When someone receives Jesus as Lord, they enter into a long-standing covenant family, borne out of God’s promise to Abraham, consummated by Christ Jesus at the cross, and extended by the Church to all peoples as an offer of grace through faith.
