Passage
And there appeared to him a messenger of the Lord standing on the right side of the altar of the perfume,
And there appeared to him a messenger of the Lord standing on the right side of the altar of the perfume,
Luke 1:9 according to the custom of the priesthood, his lot was to make perfume, having gone into the sanctuary of the Lord,
Luke 1:10 and all the multitude of the people were praying without, at the hour of the perfume.
Luke 1:11 And there appeared to him a messenger of the Lord standing on the right side of the altar of the perfume,
Luke 1:12 and Zacharias, having seen, was troubled, and fear fell on him;
Luke 1:13 and the messenger said unto him, `Fear not, Zacharias, for thy supplication was heard, and thy wife Elisabeth shall bear a son to thee, and thou shalt call his name John,
The verse centers on "appeared", "messenger", "lord", "standing", "right", "side", "altar", and "perfume". It is saying that the verse draws attention to "appeared" and "messenger", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 10's "and all the multitude of the people..." into verse 12's "and Zacharias having seen was troubled and...", so "appeared" and "messenger" 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 "appeared" and "messenger" with trust shaped by these words, not by a vague optimism outside the passage.
