It is this conviction which has nerved men to face insuperable difficulties, and achieve impossible and unhoped-for ends. It works in the spirit of the cry, "Who art thou, O great mountain? Before Zerubbabel be thou changed into a plain!" It inspires the faith as a grain of mustard seed which is able to say to this mountain, "Be thou removed, and be thou cast into the sea,"--and it shall obey. It stands unmoved upon the pinnacle of the Temple whereon it has been placed, while the enemy and the tempter, smitten by amazement, falls. In the hour of difficulty it can cry,-- "Rescue me, O Lord, in this mine evil hour, As of old so many by Thy mighty power,-- Enoch and Elias from the common doom; Noe from the waters in a saving home; Abraham from the abounding guilt of heathenesse; Job from all his multiform and fell distress; Isaac when his faither's knife was raised to slay; Lot from burning Sodom on the judgment day; Moses from the land of bondage and despair; Daniel from the hungry lions in their lair; And the children three amid the furnace flame; Chaste Susanna from the slander and the shame; David from Golia, and the wrath of Saul; And the two Apostles from their prison-thrall." The strangeness, the unexpectedness, the apparently inadequate source of the deliverance, have deepened the trust that it has not been due to accident. Once, when Felix of Nola was flying from his enemies, he took refuge in a cave, and he had scarcely entered it before a spider began to spin its web over the fissure. The pursuer, passing by, saw the spider's web, and did not look into the cave; and the saint, as he came out into safety, remarked: "_Ubi Deus est, ibi aranea murus, ubi non est ibi murus aranea_" ("Where God is, a spider's web is as a wall; where He is not, a wall is but as a spider's web"). This is one lesson conveyed in the words of Christ when the Pharisees told Him that Herod desired to kill Him. He knew that Herod could not kill Him till He had done His Father's will and finished His work. "Go ye," He said, "and tell this fox, Behold, I cast out devils, and I do cures to-day and to-morrow, and the third day I shall be perfected. Nevertheless, I must walk to-day, and to-morrow, and the day following."
