Since you are so convinced of Universalism, it seems to me, Pneuma, that somehow you have allowed yourself to be conned by a deceiving spirit into believing the doctrine of a demon:
1Ti 4:1 Now the Spirit expressly says that in latter times some will depart from the faith, giving heed to deceiving spirits and doctrines of demons,
See here that Scripture tells of the blackness of darkness being reserved forever for those who turn the grace of our God into lewdness and deny the only Lord God and our Lord Jesus Christ. Jude 1:4
Jud 1:12-13 These are spots in your love feasts, while they feast with you without fear, serving only themselves. They are clouds without water, carried about by the winds; late autumn trees without fruit, twice dead, pulled up by the roots; (13) raging waves of the sea, foaming up their own shame; wandering stars for whom is reserved the blackness of darkness forever.
Yes, I'm 100% convinced in Universal Salvation.
