The moment when a woman learns she is expecting is forever preserved in her mind. Time stands still as she contemplates the new life within her. Soon, she will share that news with her husband, family, and friends. But, for just a moment, it is hers to cherish.

In Luke 1, we read about Zacharias, Elizabeth, and Mary and others who received birth announcements. The angel Gabriel delivered these important messages both visually and verbally. God chose each person for these specific assignments because they were righteous and blameless (v. 6) and favored by God (v. 28). These calls involved a miraculous conception— because of Elizabeth’s advanced age (v. 7) and Mary’s virginity (v. 34). These individuals were called to something they could not accomplish by themselves. These calls required the work of God.

The calls included a promise that these babies would become men and change the world. John would “bring back many of the people of Israel to the Lord their God” (v. 16). And Jesus would “reign over Jacob’s descendants forever” (v. 33). Jesus’ kingdom would never end.

Gabriel gave specific instructions regarding their names. To Zacharias, he said, “You are to call him John” (v. 13). And to Mary, he said, “You are to call him Jesus. He will be great and will be called the Son of the Most High” (vv. 31–32).

This Greek word for call is kaleo, meaning to name, to invite, to call out, to assign (as in vocation). Kaleo is found throughout the New Testament. In response to God’s call, Zacharias expressed doubt (v. 18) and was disciplined accordingly. Mary, too, voiced a question. But she also declared her willingness to obey. “‘I am the Lord’s servant,’ Mary answered. ‘May your word to me be fulfilled’” (v. 38).

>> God often chooses ordinary people to do extraordinary things for His kingdom’s sake. The proper response is always obedience. What might God be calling you to do?
