I was careful not to say good luck.
I also reached the stage where I started wondering if I should be sending Christmas card that pictured Mary with Jesus as, by then, I had come to believe that "Mary worship" was associated with the Jezebel spirit.
Talk about superstition. I was nervous about wearing a cross, nervous about playing Debussy, nervous about listening to rock (even Christian rock), nervous about anything Babylonish: all those little demons waiting, ready to pounce.
