 Please get this. Before the angel could reveal the prophecy to Mary, he had to deal with her fear. Because please understand, you cannot have faith and fear operating at the same time. 2 Timothy chapter 1 and verse 7 says, For God has not given you the spirit of fear, but a power of love and a what? Sound what? Mind. So what you must understand is that what the angel had to do was cast out fear in order for her to be able to accept the fact that she was chosen to do something that would change the world. Mary could not be unstable.
