The word ‘ministry’ has become a shorthand term for spiritual service that one does full-time while receiving from a congregation or from saints. We didn’t get that from the Bible. It’s a denominational clergy-laity distinction.
“It is as a writer of gospel songs I am proud to be known, for in that way I may be of the most use to my Master, whom I serve willingly although not as efficiently as is my desire.” —C.A. Miles
There’s a big difference between being a “preacher for the church” (common, unbiblical phrase among us) and a “servant of the church” Col 1.25. One is an employee, sometimes a lackey; the other an obedient follower of the Lord Jesus.
