Passage
for which also I labour, striving according to his working that is working in me in power.
for which also I labour, striving according to his working that is working in me in power.
Colossians 1:27 to whom God did will to make known what <FI>is<Fi> the riches of the glory of this secret among the nations--which is Christ in you, the hope of the glory,
Colossians 1:28 whom we proclaim, warning every man, and teaching every man, in all wisdom, that we may present every man perfect in Christ Jesus,
Colossians 1:29 for which also I labour, striving according to his working that is working in me in power.
The verse centers on "labour", "striving", "working", and "power". It is saying that the verse draws attention to "labour" and "striving", so its meaning should be read from those terms before moving to application.
The prior verse says "whom we proclaim warning every man and...", giving immediate footing for "labour" and "striving". In Colossians context, the local focus is Christ, faith, and discipleship.
A plain takeaway is to answer the verse's own emphasis on "labour" and "striving" with trust shaped by these words, not by a vague optimism outside the passage.
