Up to that hour Isaiah was conscious only of the fact that something must be done in Judah to save it from the evils of injustice and unrighteousness that were being practiced by the rich and powerful upon the poor and weak. From that hour on he knew that God had called him to be His prophet, that God had selected him to bring the truth home to the Judeans and, if possible, to save the nation from the doom that awaited the sister-nation, Israel. What Isaiah saw and heard in the Temple at the close of that memorable day, gave him the germ of an idea as to what God demanded of him to do. Time, thought and experience ripened that idea into a plan. The course of events offered him the opportunity to put the plan into action. Isaiah could not count on Jotham to institute and carry out reforms in the religious beliefs and practices of the people, in their commercial wrongdoings, in the corrupt law courts and in the general oppression of the lower classes. He had to begin work on his own initiative; and he began it with the people themselves, in the City of Jerusalem. He came to the Temple Mount one day, when many pilgrims were gathered there. He listened attentively, with the rest, to travelers from Arabia, who were relating wonderful tales of adventure. From stories of adventure in foreign lands the pilgrims drifted into stories of happenings in their own country. Some related rumors of what was going on in Samaria; others spoke of the possibility of Judah's being forced to fight Assyria some day. Some laughed at such a suggestion; others were in grave doubt whether such an emergency would find the nation prepared. Some spoke of the evils that were sapping the strength of the people; others complained that the king, instead of attending to his business of State, was busying himself with his wealth of herds and vineyards. Here Isaiah, who had been silently listening to the discussions, offered to recite a poem, an original composition. The suggestion was received with loud applause and Isaiah began: "Let me sing a song of my friend, My friend's song about his vineyard." At this introduction everybody settled down comfortably to listen, and Isaiah continued: "My friend hath a vineyard On a fertile hill; He digged it and gathered out the atones, And planted it with choicest vine; A tower he built in the midst of it And hewed out a wine press. He looked to find grapes that were good, And it yielded only wild grapes." Isaiah's listeners were disappointed. The story not only lacked excitement, it even lacked interest. They shifted in their places uneasily, but Isaiah caught their attention again by continuing: "And now, O inhabitants of Jerusalem, And ye people of Judah. Judge, I pray you, betwixt me And betwixt my vineyard. What more could be done to my vineyard Than that which I have done? When I looked to find grapes that were good Why yielded it wild grapes?
