Passage
And immediately his mouth was opened and his tongue loosed: and he spoke, blessing God.
And immediately his mouth was opened and his tongue loosed: and he spoke, blessing God.
Luke 1:62 And they made signs to his father, how he would have him called.
Luke 1:63 And demanding a writing table, he wrote, saying: John is his name. And they all wondered.
Luke 1:64 And immediately his mouth was opened and his tongue loosed: and he spoke, blessing God.
Luke 1:65 And fear came upon all their neighbours: and all these things were noised abroad over all the hill country of Judea.
Luke 1:66 And all they that had heard them laid them up in their heart, saying: What an one, think ye, shall this child be? For the hand of the Lord was with him.
The verse centers on "immediately", "mouth", "opened", "tongue", "loosed", "spoke", and "blessing". It is saying that the verse draws attention to "immediately" and "mouth", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 63's "And demanding a writing table he wrote..." into verse 65's "And fear came upon all their neighbours...", so "immediately" and "mouth" 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 "immediately" and "mouth" with trust shaped by these words, not by a vague optimism outside the passage.
