The verse centers on "shall", "able", "withstande", "thee", "dayes", "life", and "moses". It is saying that the verse draws attention to "shall" and "able", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 4's "From the wildernesse and this Lebanon euen..." into verse 6's "Be strong and of a good courage...", so "shall" and "able" belong inside that flow. In Joshua context, the local focus is covenant, worship, and faithfulness.
A plain takeaway is to answer the verse's own emphasis on "shall" and "able" with trust shaped by these words, not by a vague optimism outside the passage.
