Study Lenses
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 provoke not your children to anger...", 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.
