Only one thing should lead one to dedicate his life to Christian work. It is the great compulsion. One has it when he is conscious that he cannot do anything else and be quite content. That was the feeling that drove Moses to the end of the wanderings of his people, that sent Jeremiah to thunder the warning to a nation drifting to its ruin, and that impelled Jesus to the tears of Gethsemane and the anguish of Calvary. The person who does not find it in his soul to give his life wholly to Jesus is to be congratulated. He will pluck many thorns, but each thorn will bear a rose. He will travel many hard paths, but he will have the joyous consciousness of being a world builder for God. 2. The Conditions of Communion. One day in 737 B.C. a young man of high social standing was in the temple at Jerusalem. There he saw a vision of the Lord upon His throne. The experience humbled the young man’s soul, cleansed his lips, and sent him forth to sound a warning to a people swiftly rushing to their doom. The temple atmosphere furnished Isaiah with the conditions of communion. About 625 B.C., when the storm clouds were still hovering near Judah, a young priest named Jeremiah saw in the presence of the Scythian army on Syrian soil the possibility of invasion by them and their Assyrian allies. He warned his people of coming destruction, at the bidding of Jehovah, who told him that he had been set apart for the task since before his birth. The peril he saw drawing near his people furnished Jeremiah with the conditions of communion. One day a young man named Jesus, His as custom was, entered the little synagogue at Nazareth. He was one who took part in the meeting. Taking the roll of the prophet Isaiah, He read from it the words of a commission to proclaim the day of God under the compulsion of the divine spirit. As He read, His heart told Him that commission was His own. Jesus heard His great challenge to duty as He stood in the place of worship reading the words of those who in earlier centuries had intimately known God. One day, still later, John saw the curtains of eternity drawn aside to reveal to him the things that must shortly come to pass. Three things made his vision possible. He was in a quiet and secluded place. It was the Lord’s Day. He was in the spirit. Such a situation is very apt to carry anyone within seeing and hearing distance of God. John met God face to face by the fulfilment of certain fundamental psychological conditions of vision and communion. On the evening of the twenty-fourth of May 1738, a young man who had believed in God all his life, but had sought vainly for a heart experience of faith, went into a meeting in Nettleton Court, on the East side of Aldersgate Street, in London. At a quarter before nine o’clock he knelt at an altar and felt his heart strangely warmed. The altar of a church furnished John Wesley with the conditions of communion. 3. The Kingdom Partnership.
