I trust your editor. Can I just accept all changes to save time?

You can, but we don't encourage it. Our editors are very skilled, but sometimes, if you have written a sentence that deliberately goes against our house stylebook (The Chicago Manual of Style), and the editor changes it, you may want to reject that change. By looking through the entire manuscript and each suggestion, you can ensure that your book retains the voice and style you wanted, while correcting any errors our editor has found.
