If an Israelite bought a Hebrew slave, he must set him free in the seventh year. But, if the slave loved his master and said, "I will not go away from thee," then a hole was to be bored through the lobe of his ear pronouncing him a bond-slave forever.
Jesus is the supreme example of selflessness - He puts others ahead of Himself.
We see from Jesus' example, that the way to exaltation in God's kingdom comes through humility and servanthood to others. His humiliation, displayed in His coming to earth as a man, is not only a lesson in Christology but also an example to all believers of what greatness in God's kingdom implies. Let this attitude of heart, taken from the example of Jesus Christ, continue to motivate all true believers in Him.
The Creator became the creation; the Lord became the servant; the Highest became the lowest. All of this was done because of God's great love for us.
