By virtue of this general ministry, all Christians are to be Christ's prophets and priests and kings. So all female Christians too are to be Christ's prophetesses and priestesses and queens in everthing they do. I Pet. 3:7 & I Cor. 10:51 with. Eccl. 3:113 & 5:18-20 & 9:7-10. See too Dr. F.N. Lee's Principles of Biblical Church Government (especially the section on "The Office of All Believers").
2. THE GENERAL MINISTRY OF ALL "SISTERS IN CHRIST"
Godly Christian women conscientiously occupying the general office of all believers, do wonderful work for the Lord and His people. One need only think of many of the very "elect ladies" mentioned in Scripture (cf. II John 1,5,13).
