He that believes on him is not condemned: but he that believes not is condemned already…
A person who had noticed a flower of a very rare kind growing on a narrow ledge on the face of a precipitous rock, was very desirous to gain possession of it. There was no possibility of reaching it except by a person being let down from the top suspended by a rope. The person interested engaged a boy of the neighbourhood, and brought him to the spot for this purpose. But the boy, when he saw the situation of the flower, hesitated. His employer tried to tempt him by the offer of a larger reward, but still he hesitated. At last, when a very considerable sum was named, he turned to the gentleman, and said, "Yes, I will get it, if I may fetch my brother to hold the rope." Here is an example of implicit trust consciously exercised under extraordinary circumstances.
(A. J. Parry.)
