OK the “a” was typographical error, but not inappropriate. I suppose we do care that the “God“ who calls someone is indeed the God whose revelation we preach.
I’m not sure I ever felt that God called me “personally” to ordained ministry. My sense of call was mediated through the Church - Sunday School Luther League, church camp, choir singing, acolyte service, attendance at worship, guidance from pastors and others who said I had the. “skills” necessary for public ministry. I was “academically” inclined, could speak well in public, was a competent volunteer in church and other places. All those things, plus prayer and study led to my sense of call. Then the synod “took over” my formation through the church vocations committee and bishop. I am especially grateful for the guidance from Dr. Alfred Biel, Iowa synod President, who got me started, and Bishop Dr Raynold Lingwall, formerly of the Augustana Lutheran Church, who ordained me. Plus three parish pastors, fine models - Ray Tiemeyer (who almost didn’t confirm me), Stan Ecklund (who talked to me a lot about preaching) and Russell Olson, (Pastor of the young woman I would marry, who taught me about social involvement).
My call came though those activities, those people.
