After some years he was sent to Florence to preach. At first his plain and severe denunciations of the prevailing sins of the time repelled the people who preferred to go where they could hear more polished and less conscience-awakening sermons, and Savonarola mourned over his apparent failure to reach the hearts of the multitude who were rushing on in the ways of sinful indulgence. But his soul was moved with zeal "for the redemption of the corrupt Florentines. He must, he would, stir them from their lethargy of sin." He was convinced that he was in the line of duty, and the more indifferent his hearers were the more anxious he grew for their awakening. Actuated by this motive he suddenly found his voice and revealed his powers as an orator. God had shown him how to reach men's hearts at last, and "he shook men's souls by his predictions and brought them around him in panting, awestruck crowds;" then at the close of his denunciations of sin, his voice would sink into tender pleading and sweetly he would speak of the infinite love and mercy of God the Father. After a time, St. Mark's Church would not hold the crowds which came to hear him and he was invited to preach in the Cathedral. He was now acknowledged as a power in Florence, and the great Lorenzo de' Medici who was then at the height of his fame as a ruler, was alarmed, and he sent a deputation of five of the leaders of the government to advise the monk to be more moderate in his preaching, hinting that trouble might follow a disregard of this advice. But the monk was unmoved. He replied, "Tell your master that although I am an humble stranger and he the city's lord, yet I shall remain and he will depart." He also declared that he owed his election to God, and not to Lorenzo, and to God alone would he render obedience. Lorenzo was very angry, but he tried to silence the monk by bribery, but Savonarola would not be bribed nor driven. He continued to preach with great fervor, denouncing sin in high places as well as in low. You know that in those times corruption had crept into the Church of Christ, and it was against these sins of the Church that his most scathing denunciations were hurled. He had many followers, and he pushed his reforms in Church and State. His enemies grew more bitter and fiercer. Remonstrances from those in authority had no effect. He was offered a cardinal's hat, but would not accept the conditions. He said, "I will have no hat but that of the martyr, red with mine own blood."
