Colossians 2:6-7

v6: To receive Jesus Christ as Lord, is to receive Him as the prophet who reveals God's will; the priest "who became the Saviour from sin and wrath by the atoning sacrifice of himself"; and the king "who they are to obey and be subjects."  If we have received Christ, we are to "walk with him" making our "way of life consistent with [our] commitment," and maintaining our fellowship with Him.

v7: "If we walk in him, we will be rooted in him; the more firmly we are rooted in him, the more closely we will walk with him."
