As you have therefore received Christ, [even] Jesus the Lord, [so] walk (regulate your lives and conduct yourselves) in union with and conformity to Him. Colossians 2:6 (AMP)
Cause-Effect. Having accepted Jesus Christ as THE Lord, then the result should be a life that is lived in accordance with Him and His Word. Sounds simple enough.
The word for "Walk" means to continue walking; carry into practice the Christ-unified life in your walk. It's a continual action. It's not "I'm saved—period, so I'll live my life as I please."
If I truly recognize Jesus Christ as THE LORD, the Messiah, the Son of God—then that should have an effect on how I live.
Unity. One. Not at odds.
How do I conform to Jesus Christ? How is that unity created? It begins at the moment of trust Jesus Christ as my Savior. Then I am to continue to get to know Christ through reading His Word, so that I can live a life that honors and glorifies God.
Cause-Effect. To conduct myself in conformity to Christ, I must be permeated with a deep sense of reverence for God (Acts 9:31; MSG).
