November 30

Verily, I beseech the Lord of Hosts to increase thy faith each day over that of the previous day, to confirm thee through His Holy Spirit, to give thee capacity to partake of the lights of knowledge and wisdom, to make thee a herald of the Covenant in those regions, and to instruct thee in that which thou knowest not; so that thou mayest become a physician for bodies as well as souls, to heal bodies with the medicines which are useful and beneficial for physical (sickness), and to cure hearts and souls with that antidote which quickeneth hearts and souls.
