662. Can we pray effectively for others?
“People who pray exercise an influence through their desire to do good. By prayer, they attract good spirits who take part in the good they desire to do.”
Through our thought and will, we possess a power of action that extends far beyond the limits of our physical world. To pray for others is an act of volition. If our will is passionate and sincere, it calls good spirits to the aid of the party prayed for, and helps that person by suggesting good thoughts and providing the strength of body and soul that he or she needs. Once again, a prayer from the heart is everything, while that of just the lips is worthless.
