Faith

"Such a favour as this it was not for her to slight, or be indifferent to; and for what God has promised he will be sought unto; by prayer we must put our amen, or so be it, to the promise. Remember, and perform thy word unto thy servant, upon which thou has caused me to hope.We must, as Mary here, guide our desires by the word of God, and ground our hopes upon it. Be it unto me according to thy word; just so, and no otherwise."

Matthew Henry

Luke 1:26-38
