you are real, show me that you are real." if you sense something at that time (and you will know it when you feel it), that is wonderful! however, if you don't sense anything, don't be alarmed. you asked god, and now it is up to him to show you that he is real. you can simply continue on your day. if you find yourself wondering again if he is real, simply ask him again. eventually, he will reveal himself to you.
