"How can I be sure this will happen? I am an old man, and my wife is well advanced in years." --Luke 1:18

Read: Luke 1

Not his best moment. Zacharias has just been given really great news; news of eternal significance. He's been told that Elizabeth will bear him a son. And he will go before the Lord with the spirit and power of Elijah, no doubt. The frontrunner! And not only that, the courier of this miracle message wasn't a neighbor. It wasn't a trusted uncle or even the High Priest. No, Zacharias heard this first-hand from none other than Angel Gabriel himself.

Now, all things being equal, you'd think that would prompt Zacharias to simply rejoice, trust and obey. But as you read in today's verse, Zacharias chose to respond like you and I often do.

Who me? I'm not qualified for that job, have you seen my resume? Who me? A missionary? Have you read my laundry list of weaknesses? Who me? Regain my health after years of negligence? What good can this body accomplish?

There's no telling how effective we would be for the Lord if we trusted the things God lays on our hearts. You know, Zacharias' little faith spoke volumes, so Gabriel made him mute. Months later, on the day of his son's birth, those standing around Elizabeth objected to his given name. But Zacharias -- still mute -- boldly wrote on his tablet: His name is John.

He got his voice back.

Question: When you and I let fear and doubt cloud our hearts and minds, we too become mute. What has God put on your heart that you need courage to accept?
