Do you not know that when you present yourselves to someone as slaves for obedience, you are slaves of the one whom you obey
Romans 6:16, portion
Although Paul here was speaking of submission to sin, he spoke of a general principle which holds true in all things. When we submit our spirits to any thing, we become its slaves. This is true, whether it is to a job, a spouse, an organization, or any other thing.
Jesus said that, for believers, we are to call no one Rabbi, Teacher, Father, Leader, or Master, for God alone is all of these things (Matthew 23:1-12). In fact, Jesus Himself said that the Gentiles even consider it to the benefit of those they are leading when they do so, and call themselves their subject’s “benefactors” (Luke 22:25). But, He said,
But it is not this way with you, but the one who is the greatest among you must become like the youngest, and the leader like the servant. For who is greater, the one who reclines at the table or the one who serves? Is it not the one who reclines at the table? But I am among you as the one who serves.
