Though Colossians 3:1-4 serves as the major transitional passage in the book, Paul already used 2:6-7 as a “mini” transition. Here Paul exhorted us to live our lives with the same “Christ Jesus the Lord” that we initially put our faith in. That is, this One, Jesus, who is Creator & Sustainer of the universe (1:16-17), who has priority & preeminence over all creation (1:15, 17), who reconciled sinful mankind to Himself & resides as Head of the church (1:22, 18) and in whom all God’s fullness dwells & all wisdom & knowledge hides (1:19; 2:3) – this One must consume our lives; we must live in Him!
Following this brief transitional command to “walk in” Jesus, Paul delays in explaining what this means & how this is done. Instead, in 2:8-23 he warns about the false teachers who seek to mislead them (see 2:8, 16-19, 20-23), while at the same time he elevates what Jesus has done and accomplished for and in us (see 2:9-15, 19). Only then does Paul describe for us how to walk in Jesus; this he does in 3:1-2.
