"you have one master"

We're starting the leadership discussion again in the church meeting tonight. I'm interested to see where it goes. And I offered to start it off by leading the worship time, using that song. Also these words of Jesus:

"You are not to be called rabbi [that is, teacher], for you have one teacher, and you are all brothers and sisters. And call no man your father on earth, for you have one Father, who is in heaven. Neither be called masters, for you have one master, the Christ." (Mt 23.8-10)
