2 Corinthians 1:24 - Ellicott's Commentary On The Whole Bible

Not for that we have dominion over your faith. — Better, are lording it over. He has scarcely written, or uttered, the words which imply authority, when the thought comes to him that he may seem to claim too much. He shrinks from “lording it over God’s heritage” (1 Peter 5:3), and half apologises for so strong a word as “sparing.” He puts forward, therefore, the other side of his work. He was really seeking, not to domineer, or cause pain, but to be a fellow-worker with their “joy and peace in believing” (Romans 15:13). He knows that they have a standing-ground, independently of him, in their faith in Christ, and he seeks to confirm that faith.
