John [Bosch] was present on November 19 at the Master's last public talk; ‘Abdu’l-Bahá pointed to John on this occasion and addressed the talk to him: He spoke of divine love, and how different it is from human love, which fails in the testing and in which there is no element of self-sacrifice. He told John that the Persian believers loved him, although they could not speak their love, and that if John went to Persia they would if necessary give up their own lives to protect his. He said: 'When lovers meet it may be that they cannot exchange a single word, yet with their hearts they speak to one another. Thus do the clouds speak to the earth and the rain comes down; the breeze whispers to the trees; the sun speaks to the eyes of men. Although this is not actual speech yet this is the way in which the hearts of the friends communicate... For instance, you were in America and I was in the Holy Land. Although our lips were still yet with our hearts we were conversing together.'
