But in the Gospel of Mark, Jesus is shown as a servant.
What does a servant do? In spite of the self-evident answer, let me simply say that a servant serves. And if you want to see what a true servant looks like, study the Gospel of Mark.
A servant places the interests of others first.
I am reminded that Jesus never used His miraculous powers to make His own life on earth comfortable. He did not hold title to a posh house in a gated community. He did not belong to the Jerusalem Country Club. The religious establishment snubbed Him. His friends were, at best, were on the fringe of society.
Jesus was not afraid of hard work. In fact, He worked Himself weary. Faithful servants do that. They work and they work hard for the benefit of others.
Had you met Jesus in a fine restaurant, no doubt, you would have found Him with the dishwasher and serving staff. And had you met Him in an office tower, you would have likely seen Him in the company of the janitorial and maintenance crews. He did not have others waiting on Him. On the contrary, He cared for the needs of others.
We serve not for reward, but we serve out of devotion to Him. There are rewards to serving others in the name of Jesus Christ, but a servant who serves from a mercenary heart will never see the benefit of his or her efforts.
