And so it came to pass that this great sinner became one of God's saints and did a wonderful work for Him in the world. He was made Bishop of Hippo, and was one of the most famous bishops the world has ever known. There is one legend told of Augustine which has comforted many hearts when puzzling questions have arisen and it has seemed so difficult to understand all the Bible teaches us about our Father in heaven. They say that once when this great father of the Church was walking along by the seashore, troubled and perplexed because he could not understand many things about God, he came upon a little child playing there alone. The child had digged a hole in the sand and was carefully filling it with water which he brought from the sea in a spoon. The bishop stopped and watched him for a while and then he asked: 'What art thou doing, my child?' 'I mean to empty the sea into my hole,' answered the child, busily going backwards and forwards with his spoon. [Illustration: THE CHILD HAD DIGGED A HOLE IN THE SAND.] 'But that is impossible,' said the bishop. 'Not more impossible than that thy human mind should understand the mind of God,' said the child, gazing upwards at him with grave, sweet eyes. And before the bishop could answer the child had vanished, and the saint knew that God had sent him as an answer to his troubled thoughts, and as a rebuke for his trying to understand the things that only God could know. SAINT AUGUSTINE OF CANTERBURY It was market-day in the great city of Rome, and the people were busy buying and selling and shouting, just as they do to-day with us, when market-day comes round. But there was a great difference between this Roman market and ours, a difference which would have seemed to us strange and cruel. For instead of sheep and oxen, or green vegetables from the country, they were selling men and boys, and even little maidens. There in the great market-place, with the sun beating down on their bare heads, they stood, looking with dull, despairing eyes, or with frightened glances at the crowds of buyers and sellers who were bargaining around. Suddenly a hush fell on the crowd, and a stately figure was seen crossing the square. People stood aside and bent their heads in reverence as Gregory passed by, for he was Abbot of a great monastery in Rome, and was much beloved even by the rough Roman soldiers. He walked swiftly as if he did not care to linger in the market-place, for it grieved his gentle heart to see the suffering of the slaves when he could do nothing to help them.
