Every leader serves something or somebody. Many leaders serve primarily their own interests. Some prioritize the interests of the organization. Few put the interests of their staff and serve their growth more than their own interests.
There was no greater servant leader than Jesus Christ. He says:
Whoever wants to become great among you must be your servant, and whoever wants to be first must be your slave-just as the Son of Man did not come to be served, but to serve, and to give his life as a ransom for many. (Matthew 20:26-28)
The vital question for you as a leader is: Who do you serve?
