In this wonderful passage are laid down principles of religious preaching, which are good for all time. But where are the Teachers with such qualifications? We must invite all to the Way of Allah, and expound His Universal Will; we must do it with wisdom and discretion, meeting people on their own ground and convincing them with illustrations from their own knowledge and experience, which may be very narrow, or very wide. Our preaching must be, not dogmatic, not self-regarding, not offensive, but gentle, considerate, and such as would attract their attention. Our manner and our arguments should not be acrimonious, but modelled on the most courteous and the most gracious example, so that the hearer may say to himself, "This man is not dealing merely with dialectics; he is not trying to get a rise out of me; he is sincerely expounding the faith that is in him, and his motive is the love of man and the love of Allah."
