Philip told me that when he was diagnosed with Parkinson's disease, after the doctor left the room, he got on his knees and accepted the announcement in prayer. He knew it was a Word from God and welcomed it from the Father who loves us. Ahaz would not even consider an announcement from God. There was no room for God. His Word could not find a home there.
Annunciations can be great.
We can welcome them, but they are just the beginning. The labor of obedience is just that. Obedience to the Word brought Mary to the foot of the Cross. She is the first of the redeemed. This will was for us to be made holy by the offering of the body of Jesus Christ made once and for all.
