Passage
There shall not any man be able to stand before thee all the days of thy life: as I was with Moses, so I will be with thee: I will not fail thee, nor forsake thee.
There shall not any man be able to stand before thee all the days of thy life: as I was with Moses, so I will be with thee: I will not fail thee, nor forsake thee.
Joshua 1:3 Every place that the sole of your foot shall tread upon, that have I given unto you, as I said unto Moses.
Joshua 1:4 From the wilderness and this Lebanon even unto the great river, the river Euphrates, all the land of the Hittites, and unto the great sea toward the going down of the sun, shall be your coast.
Joshua 1:5 There shall not any man be able to stand before thee all the days of thy life: as I was with Moses, so I will be with thee: I will not fail thee, nor forsake thee.
Joshua 1:6 Be strong and of a good courage: for unto this people shalt thou divide for an inheritance the land, which I sware unto their fathers to give them.
Joshua 1:7 Only be thou strong and very courageous, that thou mayest observe to do according to all the law, which Moses my servant commanded thee: turn not from it to the right hand or to the left, that thou mayest prosper whithersoever thou goest.
The verse centers on "shall", "able", "stand", "before", "thee", "days", "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 wilderness and this Lebanon even..." 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.
