Passage
Children, obey your parents in all things, for this is well-pleasing in [the] Lord.
Children, obey your parents in all things, for this is well-pleasing in [the] Lord.
Colossians 3:18 Wives, be subject to [your] husbands, as is fitting in [the] Lord.
Colossians 3:19 Husbands, love your wives, and be not bitter against them.
Colossians 3:20 Children, obey your parents in all things, for this is well-pleasing in [the] Lord.
Colossians 3:21 Fathers, do not vex your children, to the end that they be not disheartened.
Colossians 3:22 Bondmen, obey in all things your masters according to flesh; not with eye-services, as men-pleasers, but in simplicity of heart, fearing the Lord.
The verse centers on "all things", "children", "obey", "parents", "well-pleasing", and "lord". It is saying that the verse draws attention to "all things" and "children", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 19's "Husbands love your wives and be not..." into verse 21's "Fathers do not vex your children to...", so "all things" and "children" 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 "all things" and "children" with trust shaped by these words, not by a vague optimism outside the passage.
