They that thirst for the wine of certitude must cleanse themselves of all that is earthly, their ears from idle talk, their minds from vain imaginings, their hearts from worldly affections, their eyes from that which will perish. They should put their trust in God, and hold fast unto Him, follow in His way. Then, they will be made worthy of the effulgent glories of the sun of divine knowledge and understanding, and become the recipients of a grace that is infinite and unseen. Inasmuch as unto the knowledge of the All Glorious, can quaff from the stream of divine knowledge and wisdom.
