Charles Spurgeon Commentary Luke 1:20

"And behold, thou shalt be silent and not able to speak, until the day that these things shall come to pass, because thou believedst not my words, which shall be fulfilled in their season." — Luke 1:20 (ASV)

Shall be performed, because you believe not my words, which shall be fulfilled in their season.

Many a child of God is unable to speak because of unbelief. Mary believed, and therefore she sang a holy, joyous song—a sweet canticle of delight: My soul does magnify the Lord. But Zacharias, because of his unbelief, was unable to speak. I wonder whether there is a man here who might have spoken for his God with power, but whose mouth is closed because of his unbelief. If so, may the Lord hasten the time when his inability to speak will be ended!
