In starting my new religion can I predict and prophecy that there will be mockers, or that one already taken?

Go for it, but you will lose in the case of miracles. God authenticated all the major events in the Bible with miracles. You can try to replicate the truth but you will fail because Gods ways are so far advanced to mans ways it makes your head spin. The fact that you are trying to replicate the truth is proof you know the truth but are rejecting the truth.
