Luke 1:57-66:

57 Now Elizabeth’s full time came for her to be delivered, and she brought forth a son. 58 When her neighbors and relatives heard how the Lord had shown great mercy to her, they rejoiced with her. 59 So it was, on the eighth day, that they came to circumcise the child; and they would have called him by the name of his father, Zacharias. 60 His mother answered and said, “No; he shall be called John.” 61 But they said to her, “There is no one among your relatives who is called by this name.” 62 So they made signs to his father—what he would have him called. 63 And he asked for a writing tablet, and wrote, saying, “His name is John.” So they all marveled. 64 Immediately his mouth was opened and his tongue loosed, and he spoke, praising God. 65 Then fear came on all who dwelt around them; and all these sayings were discussed throughout all the hill country of Judea. 66 And all those who heard them kept them in their hearts, saying, “What kind of child will this be?” And the hand of the Lord was with him.

1. In this passage we see that out of obedience, they broke tradition and named the baby John. Often, when God does a work, traditions are broken and may not make sense immediately to those around. Think of two to three examples of other places in the Bible where we see this happen. 
2. The obedience of the parents and willingness to step out side of tradition, the miracle of John being born to older parents, and the restoration of Zach’s voice, brings those around to marvel.  Do you think if Zacharias and Elizabeth hadn’t been obedient that this story would still be a testimony that caused people to fear and marvel at God? What if they had doubted and kept tradition?
3. We also see that once Zacharias obeyed, his voice was restored. Obedience to God brings restoration!  Are you needing restoration in an area of your life? Are you being obedient to what God has asked you to do?
