Study Lenses
The verse centers on "through", "died", "might", and "live". It is saying that the verse draws attention to "through" and "died", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 18's "For if I build up again those..." into verse 20's "I have been crucified with Christ and...", so "through" and "died" belong inside that flow. In Galatians context, the local focus is Christ, faith, and discipleship.
A plain takeaway is to answer the verse's own emphasis on "through" and "died" with trust shaped by these words, not by a vague optimism outside the passage.
