How does Mary respond to the word of God delivered by the angel Gabriel? She knows she is hearing something beyond human capability. It will surely take a miracle which surpasses all that God has done previously. Her question, “how shall this be, since I have no husband” is not prompted by doubt or skepticism, but by wonderment! She is a true hearer of the Word and she immediately responds with faith and trust. Mary's prompt response of "yes" to the divine message is a model of faith for all believers. Mary believed God's promises even when they seemed impossible. She was full of grace because she trusted that what God said was true and would be fulfilled. She was willing and eager to do God's will, even if it seemed difficult or costly. Mary is the “mother of God” because God becomes incarnate when he takes on flesh in her womb. When we pray the Nicene Creed we state our confession of faith in this great mystery: “For us men and for our salvation he came down from heaven; by the power of the Holy Spirit, he became incarnate of the Virgin Mary, and was made man.” God gives us grace and he expects us to respond with the same willingness, obedience, and heartfelt trust as Mary did. When God commands he also gives the help, strength, and means to respond. We can either yield to his grace or resist and go our own way.
