Passage
And *thou*, child, shalt be called [the] prophet of [the] Highest; for thou shalt go before the face of [the] Lord to make ready his ways;
And *thou*, child, shalt be called [the] prophet of [the] Highest; for thou shalt go before the face of [the] Lord to make ready his ways;
Luke 1:74 to give us, that, saved out of the hand of our enemies, we should serve him without fear
Luke 1:75 in piety and righteousness before him all our days.
Luke 1:76 And *thou*, child, shalt be called [the] prophet of [the] Highest; for thou shalt go before the face of [the] Lord to make ready his ways;
Luke 1:77 to give knowledge of deliverance to his people by [the] remission of their sins
Luke 1:78 on account of [the] bowels of mercy of our God; wherein [the] dayspring from on high has visited us,
The verse centers on "called", "thou", "child", "shalt", "prophet", and "highest". It is saying that the verse draws attention to "called" and "thou", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 75's "in piety and righteousness before him all..." into verse 77's "to give knowledge of deliverance to his...", so "called" and "thou" belong inside that flow. In Luke context, the local focus is Christ, faith, and discipleship.
A plain takeaway is to answer the verse's own emphasis on "called" and "thou" with trust shaped by these words, not by a vague optimism outside the passage.
