In the life of Moses, the BURNING BUSH was a MYSTIC event (as well as some of the "magic" he performed in Egypt).
For Mother Teresa, she had the initial apparition from Heaven that ordered her to form the Missionaries of Charity.
Then there is the MYSTIC EVENT of the ceasing of fighting in Beirut, Lebanon, in 1982.
In the latter event, Mother Teresa tried to get a cease fire by talking to people so that she might save some retarded Muslim children.
She was told that nobody could order a cease fire. At that point, she went and prayed in the next room and said that there would be a CEASE FIRE at 6am the next day, and that she needed to have vehicles ready to cross into the Muslim side.
The cease fire did occur at 6 am, and only heaven knows why it happened...
Wow! I had forgotten about this, or else it never got into my mind to remember.
(As for Theresa, each person's walk is that person's and it is a matter directly between God and that person and no other, thank God for her.)
