The purpose of life is to live to the extent and extant of what God has exposed you to. You do not have to verify your existence to anyone but God. Know that you owe no man your soul. You owe your soul to God only. Love God first and yourself. What men seek to do to you is nothing to what God can do to you. He allows us to be free. Stay away from people who do not let you be yourself and be free to express your own nature.
