In verse 59-65, the baby was about to be changed to another name aside the name the angel gave to him, but thank God Zechariah was around to give him the correct name.
There are people out there who name a child wrongly and that has been working against the child. They saw that he was dumb and wouldn't be able to name the child,he requested for a pen and book and immediately he write the name JOHN, his mouth was loosed.
We need to always ask God when giving a child name so that the wrong name won't work against him
