If you go to Switzerland, you will be able to see for yourself how a great river as it rushes along its course washes away the soil. The Rhone, when it enters the Lake of Geneva, is so laden with mud that its waters are brown and turbid. For some distance you can trace the course of this brown water as it makes its way through the deep blue of the lovely lake, not mingling with it--but by the time the river reaches the other end of the lake it has rid itself of its burden: the mud has sunk to the bottom, and the Rhone flows out a clear stream. This is a strange and beautiful sight which perhaps you may see some day. Have you ever noticed how often the sea is mentioned in the New Testament? We read of the Lord Jesus walking beside it, and sailing over it in the boat with His disciples. And I daresay you remember how He once sat in the boat upon the sea, while He taught the people who were upon the shore. The Sea of Galilee must have been calm and quiet then, but it was not always so. Travellers tell us a great deal about the beauty of this lake, when the sky is clear, and the crimson bloom of the Oleanders is reflected in the still water. But they speak also of the sudden and dangerous storms, which rush down from the mountains, and turn the glassy lake into a raging sea. In the gospel by Mark we read of just such a storm of wind, when the Lord Jesus Christ was in the little boat with His disciples crossing over to the other side. It was such a terrible storm, that the waves dashed into the boat until it was filled with water. "And all but One were sore afraid Of sinking in the deep; His head was on a pillow laid, And He was fast asleep." Yes, amid all the tumult and alarm, the Saviour who was often weary in this sad world, was sleeping upon the cushion of the boat. He slept on until the disciples came and awoke Him with their cry, "Master, carest Thou not that we perish?" Then the voice of the Lord was heard above the rage of wind and water, and their cry of terror, as He rose and rebuked the wind, and said unto the sea, "Peace, be still." The proud waves obeyed that voice of power, the wind was hushed, "and there was a great calm." Do you remember what the Lord said to His disciples, and what they said to one another, as they "feared exceedingly"?
