…these [Letters of the Living] were, ere their dispersal, summoned to the Báb's presence, Who addressed to them His parting words, entrusted to each a specific task, and assigned to some of them as the proper field of their activities their native provinces. He enjoined them to observe the utmost caution and moderation in their behavior, unveiled the loftiness of their rank, and stressed the magnitude of their responsibilities. He recalled the words addressed by Jesus to His disciples, and emphasized the superlative greatness of the New Day. He warned them lest by turning back they forfeit the Kingdom of God, and assured them that if they did God’s bidding, God would make them His heirs and spiritual leaders among men.
