As ye have therefore received Christ Jesus the Lord, so walk ye in him:
'As therefore ye received (once for all: Colossians 1:7: aorist, from Epaphras) Jesus the Christ as your Lord (cf. 1 Corinthians 12:3; 2 Corinthians 4:5; Philippians 3:8), so walk in Him: as the element of your walk' (Galatians 2:20). Not merely, "ye received" the doctrine, but "Jesus" Himself (Ephesians 4:20), the essence of faith (John 14:21; John 14:23; Galatians 1:16). Ye received once for all the Spirit of life in Christ: carry that life into your walk (Galatians 5:25): the main scope of the letter.
