“The plan was going to happen whatever choice Mary made. The angel starts by saying God was with with her (even though she was troubled He was still with her). Then He tells her she is going to be with child and give birth to the Son of the Most High.
I don’t see God leaving the plan up to her choice.
She then believed the message and said she had been blessed by Him.”

God has given everyone free will, Mary too. Your love for
Him, your choice for Him would be nothing if it wasn’t freely given. Mary could of said no.
The false teaching of “faith alone” messes up things in
every area of faith. People professing God does it all,
no. With the help of His grace and our free will choices,
our cooperation with His grace.
The angel told Mary the baby would be born to her. That was not in question.
