Passage
And thou shalt haue ioy and gladnes, and many shall reioyce at his birth.
And thou shalt haue ioy and gladnes, and many shall reioyce at his birth.
Luke 1:12 And when Zacharias sawe him, he was troubled, and feare fell vpon him.
Luke 1:13 But the Angel saide vnto him, Feare not, Zacharias: for thy prayer is heard, and thy wise Elisabet shall beare thee a sonne, and thou shalt call his name Iohn.
Luke 1:14 And thou shalt haue ioy and gladnes, and many shall reioyce at his birth.
Luke 1:15 For he shalbe great in the sight of the Lord, and shall neither drinke wine, nor strong drinke: and he shalbe filled with the holy Ghost, euen from his mothers wombe.
Luke 1:16 And many of the children of Israel shall he turne to their Lord God.
The verse centers on "thou", "shalt", "haue", "gladnes", "shall", "reioyce", and "birth". It is saying that the verse draws attention to "thou" and "shalt", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 13's "But the Angel saide vnto him Feare..." into verse 15's "For he shalbe great in the sight...", so "thou" and "shalt" 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 "shalt" with trust shaped by these words, not by a vague optimism outside the passage.
