God brought the world into being, designed a beautiful earth and placed man into it. This was service.
He preserves all creation and maintains the universe:
God is taking care of humanity, he is serving mankind.
After the fall of humanity into sin, he chose a people for himself. He served them by giving them just laws, providing for them and protecting them. Through the wilderness, through the sea, God was their shield.
Upon entering into our world, he took on the humble and lowly form of a servant. He served by teaching and healing; he served by feeding and delivering. His was a life of loving service. And he taught us to do the same. Shortly before his ultimate service on the cross, he imprinted the duty of service upon the hearts of his disciples in a symbolic act of foot-washing. That night he was betrayed by one of those he had faithfully served and led away to conclude his great work of redemptive service. He did not remain in the grave, however. He rose again, poured out his Spirit upon his Church and has commanded all who confess his name to go out and transform the world through service.
He left us with an incident highlighting this great lesson:
Now there was also a dispute among them, as to which of them should be considered the greatest. And He said to them, “The kings of the Gentiles exercise lordship over them, and those who exercise authority over them are called ‘benefactors.’ But not so among you; on the contrary, he who is greatest among you, let him be as the younger, and he who governs as he who serves. For who is greater, he who sits at the table, or he who serves? Is it not he who sits at the table? Yet I am among you as the One who serves.
