Passage
Which thou hast prepared before the face of all people,
Which thou hast prepared before the face of all people,
Luke 2:29 Lord, nowe lettest thou thy seruaunt depart in peace, according to thy woorde,
Luke 2:30 For mine eyes haue seene thy saluation,
Luke 2:31 Which thou hast prepared before the face of all people,
Luke 2:32 A light to be reueiled to the Gentiles, and the glory of thy people Israel.
Luke 2:33 And Ioseph and his mother marueiled at those things, which were spoken touching him.
The verse centers on "thou", "hast", "prepared", "before", "face", and "people". It is saying that the verse draws attention to "thou" and "hast", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 30's "For mine eyes haue seene thy saluation..." into verse 32's "A light to be reueiled to the...", so "thou" and "hast" 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 "thou" and "hast" with trust shaped by these words, not by a vague optimism outside the passage.
