Passage
You also once walked in those, when you lived in them;
You also once walked in those, when you lived in them;
Colossians 3:5 Put to death therefore your members which are on the earth: sexual immorality, uncleanness, depraved passion, evil desire, and covetousness, which is idolatry;
Colossians 3:6 for which things’ sake the wrath of God comes on the children of disobedience.
Colossians 3:7 You also once walked in those, when you lived in them;
Colossians 3:8 but now you also put them all away: anger, wrath, malice, slander, and shameful speaking out of your mouth.
Colossians 3:9 Don’t lie to one another, seeing that you have put off the old man with his doings,
The verse centers on "once", "walked", and "lived". It is saying that the verse draws attention to "once" and "walked", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 6's "for which things sake the wrath of..." into verse 8's "but now you also put them all...", so "once" and "walked" belong inside that flow. In Colossians context, the local focus is Christ, faith, and discipleship.
A plain takeaway is to answer the verse's own emphasis on "once" and "walked" with trust shaped by these words, not by a vague optimism outside the passage.
