We know that empty barrels make the most noise, simply because they are empty.
So when a discussion begins to turn into an argument, there will only be noise.
Because in an argument, almost everyone will be raising their voice or even shouting, and no one is really listening.
When an argument started between the disciples about which of them was the greatest, it can be supposed that there was a lot of noise.
Because, in order to prove that he is the greatest, one would have to shout the loudest in order to drown out the rest.
Obviously their argument reached the ears of Jesus and He had to teach them about what is greatness.
Jesus said that the least among all is the greatest, and He set before them a little child as an example.
Indeed the least is the greatest, not in the eyes of men, but in the eyes of God.
Because the least can only depend on God as there is no one else to come to their help.
God comes to the aid of the lowly and the last, and on those humble enough to trust and depend on Him.
May we have that humility and God's greatest blessings will come upon us.
