Luke 1:18 (KJV)

What does Luke 1:18 mean?

Luke 1:18 shows Zacharias questioning the angel’s message that he and his wife will have a child, expressing doubt because both he and his wife are old. Zacharias asks for a sign or proof, since their age makes the promise seem impossible to him.

In this verse, Zacharias is speaking directly to an angel who has just told him that his wife Elizabeth will bear a son. The setting is the temple, where Zacharias is serving as a priest. His response reveals his uncertainty and human hesitation when faced with a miraculous promise, highlighting the natural struggle to trust what seems impossible.

The Greek behind Luke 1:18

• "ἐν γήρει" (en gērei, translated here as "well stricken in years"): This phrase literally means "advanced in days" or "gone forward in age," emphasizing not just old age but being far along in years. It underlines how unlikely childbirth seems for Zacharias and Elizabeth.
• "Γνώσομαι" (gnōsomai, "shall I know"): The Greek here carries the sense of "How will I come to know?" or "How can I be sure?" Zacharias is not just curious; he is asking for assurance or evidence, which shows his doubt.
• "Κατὰ τί" (kata ti, "whereby"): This is often understood as "by what" or "how," focusing on the means or proof by which Zacharias could believe the angel’s message. It signals a request for a sign or confirmation.

Why Luke 1:18 matters

• Luke 1:18 highlights the very human tendency to doubt even when faced with a clear message from God, especially when circumstances seem impossible.
• This verse sets up the contrast between Zacharias’s response and Mary’s later response to a similar announcement, helping readers see different ways people react to God’s promises.
• The verse also explains why Zacharias is later rendered mute: his request for a sign is rooted in disbelief rather than faith, which becomes a key point in the unfolding story.
