The verse centers on "sanctify", "great", "name", "profaned", "gentiles", and "midst". It is saying that the verse draws attention to "sanctify" and "great", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 22's "Therefore thou shalt say to the house..." into verse 24's "For I will take you from among...", so "sanctify" and "great" belong inside that flow. In Ezekiel context, the local focus is covenant, worship, and faithfulness.
A plain takeaway is to answer the verse's own emphasis on "sanctify" and "great" with trust shaped by these words, not by a vague optimism outside the passage.
