Let canvassers be faithful students, learning how to make their work successful; and while thus employed, let them keep their eyes and ears and understanding open to receive wisdom from God, that they may know how to help those who are perishing for lack of a knowledge of Christ. Let every worker concentrate his energies and use his powers for the highest of all service, to recover men from the snare of Satan and bind them to God, making the chain of dependence through Jesus Christ fast to the throne encircled with the rainbow of promise.—Manual for Canvassers, 35-39.
