What does Colossians 2:7 mean?
Paul provides three images that show the importance of walking in faith (Colossians 2:6). First, we are "rooted" in Christ. The idea is that of a tree or plant whose roots form the strength and basis for life. The believer's roots are Christ, not another source, as false teachers would suggest. Second, the believer is "built up" in Christ. This building or architectural metaphor speaks of a building that is constructed by the power of Christ. Just as only Christ can save a person, only Christ can build up or mature a person. Third, to be "established" in the faith is a legal metaphor referring to maturity or something firmly decided.The second half of the verse refers again to Epaphras, the man who brought Christianity to the Colossians. His outreach to these people included the true gospel, in contrast with the false teachings Paul is about to address. The result of the true gospel of Jesus is thanksgiving (Colossians 1:3; Colossians 4:2).
