Colossians 2:6

As ye have therefore received. “As” refers to the manner in which they had received the message of salvation preached by Epaphras (Colossians 1:7).

Christ Jesus the Lord. These three titles of the Messiah gather within themselves the fullness of His position and functions. His mission as Saviour is embodied in the name “Jesus” (Matthew 1:21). “Christ” suggests His Messianic office, and “Lord” (see on 1 Corinthians 12:3) His identification with, in some instances at least, the Yahweh of the OT.

Walk. Gr. peripated, “to conduct oneself” (see on Ephesians 2:2). Paul urges the believers to keep on continuously conducting themselves and their affairs within the sphere marked out by their trust in Jesus, doing only what He would do, and interesting themselves exclusively in the things that would please Him.
