Luke 1:38 “Then Mary said, “Behold the maidservant of the Lord! Let it be to me according to your word.” And the angel departed from her.”
Luke may have interviewed Mary. In any case it seems likely this account came straight from her mouth. And it is a great testimony to her faith.
Heavenly Father, thank You for working in our lives. Sometimes, as with Mary, You ask us to do something big. May we have the faith she had! In the Name of the Lord Jesus Christ I pray and praise You, Amen.
