Luke 1:18

And Zacharias said unto the angel, Whereby shall I know this? for I am an old man, and my wife well stricken in years.

Luke 1:18 (KJV)

Context

Luke 1:18 is part of the narrative about the birth of John the Baptist. The angel Gabriel appeared to Zacharias, a priest, and announced that his wife Elizabeth would conceive and bear a son, even though they were both advanced in years. Zacharias, in response to the angel’s proclamation, expressed doubt and asked for a sign to confirm the message.

Meaning

Zacharias’s question, “Whereby shall I know this?” reveals a moment of human weakness. He was a righteous man, yet his doubt surfaced when the promise seemed contrary to natural circumstances. The angel’s announcement came as an answer to prayer, yet Zacharias still sought a sign. His doubt is a reminder that human unbelief often stands in contrast to God’s faithful word. The sign he received—being struck mute until the promise was fulfilled—demonstrates that God’s word will stand regardless of human doubt.

Application

Zacharias’s doubt serves as a reminder for us to trust in God’s promises, even when circumstances seem impossible. God’s power and ability to work miracles are not limited by our age, capabilities, or human understanding. When God makes a promise, we can have confidence that He will bring it to pass, regardless of the challenges or obstacles we may face.

While it is natural for humans to have doubts, doubt can hinder one’s faith and trust in God’s ability to work miracles. Our faith should not be dependent on visible evidence or human reasoning but should be grounded in the power and faithfulness of God. Even in moments of doubt, God can still accomplish His purposes.

Reflection

Zacharias’s momentary unbelief serves as a warning against allowing age or circumstance to overshadow faith. The verse ultimately glorifies God’s sovereignty and faithfulness, as His purposes are accomplished despite human frailty. We are encouraged to hold fast to our faith and believe that God can accomplish the miraculous in our lives.
