A Brief Biography is found in link below:
Most Christians don’t realize that he initially believed in “eternal hell” but towards the latter part of his matured spiritual life, God Showed him the Truth of Christian Universalism in Lord Jesus Christ alone through significant supernatural visions of the spirit world.
Here’s an image highlighting this part from the link itself:
Also, here are additional images proving Christian Universalism in his other rarely known quotes from his own letters and conversations as recorded in his earliest biographies too:
Knowing that Lord Jesus Christ saves all men eventually (from Hell itself be it some from the Lake of Fire later, in the “age(s) to come” – post Judgment as well) as prophesied (implied) in Verse below agreeing to his Visions sounds pretty important to a Proper Theological Understanding for me:
“Who will have all men to be saved, and to come unto the knowledge of the truth.” – apostle Paul (1 Timothy 2:4, KJV)
Blessed be the Savior of All Men, Lord Jesus Christ!

His Mercy > Judgment
A Prophecy Regarding Lord Jesus Christ (in image) which makes ‘sense’ simply because people are ‘hating Him’ Who Alone cares enough to Save them (be it from Hell or the Lake of Fire itself) via His Mercy which can Triumph (and end) any afterlife Judgment Sentence, be it the eternal hell sentence itself:
“For judgment will be merciless to one who has shown no mercy; mercy triumphs over judgment.” (James 2:13, NASB)
Yes, the Verse above clearly implies that in the context of the Worst Judgment (without mercy may have to be endured first in the afterlife) but yet, His Mercy Triumphs (and ends) any afterlife Judgment Sentence thereafter.
