There are no guarantees. But within the first month, you will probably have at least one big surprise. If you have some experience that seems to be supernatural, evaluate it. If your experience makes you feel loved, safe, humble, and more willing and able to turn in love to those who will not love you back, you've gotten what you sought and your life will be better for it. If you feel strongly directed to do something, and it's in conjunction with an experience like this, and it seems reasonable and doesn't hurt anybody, then do it.
Calls come with a weird, pleasant, humbling, safe feeling.
If your experience makes you feel important, powerful, flattered, or entitled, or if you find yourself thinking you are innately better than anybody else, or if you find yourself believing something that doesn't make sense or is unscientific, or if you find yourself believing that you should hate somebody, your experiment has taken a wrong turn. Talk to a decent pastor before continuing. Again, this experiment is secret. If anybody remarks on a change in your behavior, deny everything. If this is impossible, then give some lame explanation or say that you don't know what's going on either.
