Romans 12:4-6

For just as in one body we have many members (natural capacities), and all the members do not have the same function, So we all are one body in Moshiach, and are individually members one of another, Having matanot (gifts) which differ in accordance with the chesed (unmerited favor, grace) given to us. If we speak for G-d as nevi'im (prophets), it should be in proportion to the emunah given to us.
