New Defender's Study Bible Notes
1:27 conversation. See note on Philippians 3:20. It is a different word from that translated “conversation” in II Corinthians 1:12 (q.v.).
1:27 becometh. A more modern way of saying this is: “Let your civic behavior be becomingly appropriate to your allegiance to the gospel.” One who professes salvation from sin and has received imputed righteousness should live in a victoriously godly life style.
