Actually, neither would I.
The Bible says to go into your closet and pray. That means, of course, you pray by yourself. It's between you and God and no one else. And neither are the results anyone else's business. If God wants a big deal made out of it, He'll (She'll) let you know. However, He/She doesn't want people to believe/come to Him/Her because of some miracle. He/She wants someone to come because of faith and love. God calls the ones He/She wants. He/She opens their hearts to receive the message.
