So you’re going to be a prophet? Your heroes are Moses, Joshua, David, Jesus, Joan of Arc, or Joseph Turner? Two words: religious zeal. You believe in a higher power, and that power speaks to you. Literally. It offers you advice and it requires service. You answer to no one but the divine power that called you, and the morals that guide you.
Your deity has goals, and you are the instrument of those goals in the world of mortals. The three basic goals of prophets are to restore the world to right, quest to find a relic, and advise the faithful—or, more likely, warn those who are no longer faithful.
You’re likely to combine those three goals in some way. Your character might go on a vision quest, discover that they need to find the rightful heir of the divine throne, and then restore the heir to the throne.
Or you might be on a quest to discover the reason for a lengthy drought, discover that it was some failure on the part of the faithful, and then restore the faithful to service so that the rain will fall again.
Be steadfast and faithful to the divine: other characters may do one thing today and another tomorrow; they can be different when no one is watching. Your prophet will remain true to their morals in all situations. Be strong in the face of moral equivocation.
Be outspoken when the gods are angered. It is in times of darkness that moral light must shine. Whether it leads to the cross or to wise old age, your prophet has a lesson to impart.
Don’t be afraid to call down the wrath of god when you are in the service of the divine. Preach if your religion expects it. Give moral answers to moral dilemmas. Pray before you go into battle, before you embark on a journey, and whenever you need divine guidance.
