So Jesus decides to teach them a true principle:
"Ye know that they which are accounted to rule over the Gentiles exercise lordship over them; and their great ones exercise authority upon them.
"But so shall it not be among you: but whosoever will be great among you, shall be your minister:
"And whosoever of you will be the chiefest, shall be servant of all."
And then, what I love so much, is that Jesus never tells people to do things He wouldn't do Himself. The next moment they happen upon a blind man, crying out for Jesus of Nazareth to heal him.
Those around Jesus, most likely including the apostles, "charged [the blind man] that he should hold his peace." But Jesus did not tell the man to hold his peace. He said:
"Be of good comfort, rise...Go thy way, thy faith hath made thee whole."
And the man immediately received his sight.
Service is one of those principles that is essential to not just be discusses, but must be lived! If we preach and teach about serving others in our church classes or talks, and then turn out backs on the blind of the world, we cannot count ourselves in the ranks of Christ -- a man who lives what He preaches.
