Study Lenses
The verse centers on "nations", "shall", "lord", "sanctifier", "israel", "sanctuary", and "midst". It is saying that the verse draws attention to "nations" and "shall", so its meaning should be read from those terms before moving to application.
The prior verse says "And my tabernacle shall be with them...", giving immediate footing for "nations" and "shall". In Ezekiel context, the local focus is covenant, worship, and faithfulness.
A plain takeaway is to answer the verse's own emphasis on "nations" and "shall" with trust shaped by these words, not by a vague optimism outside the passage.
