We need to show “real love and tolerance towards the ideas and customs of the people” and through “wise conduct and loving-kindness” remove “obstacles between them and the Truth”

Shoghi Effendi approves of your consideration for your husband. He hopes that through your wise conduct and loving-kindness to him, he will also gradually understand the significance of the Holy Cause. People are not naturally against the Truth. There are obstacles between them and the Truth. These obstacles must be wisely removed and then they surely will be attracted to the Cause. The magnet for this attraction is real love and tolerance towards the ideas and customs of the people. We must follow our Lord, 'Abdu'l-Baha, who taught us to be well-wishers of mankind disregarding religious and racial differences. Our love must be so spacious as to engulf the whole of the people of the world. With love and only with unlimited love we have been and will be able to conquer the hearts of the people and direct the current of their sentiments along the channel of the happiness of mankind and thus usher in the era of the regeneration of man. It is unlimited love which is the Elixir that turns the common metals of the human being into pure gold.
