@NickolaosPappas , while I have 6 tabs open with links to George MacDonald’s sermons, I recommend “Justice” for a view of universal salvation that is not what is commonly thought of, and might just raise the hair on the back of your neck. You can find it here: George MacDonald: Unspoken Sermons Third Series - Christian Classics Ethereal Library .
You might want to take a look at Merv’s thread here: MacDonald (selections from Lewis) - #25 by Mervin_Bitikofer . Start at this post on “Divine Burning” which you may find more than satisfies your desire for all to get what they have coming to them. Merv also included the link to the entire sermon, if you feel the need for more.
