While it is my hearts desire that all men be saved, the bible does not specifically state that salvation is universal.
The second century theologian Origen was a universalist and and Carl Barth was a hopeful universalist. But Barth was not a universalist in the true sense of the word. He only hoped that all men would be saved and we can all share his sentiment.
I sincerely hope that all men will be saved but some might reject Christ and lose their salvation.
If every man and woman will be saved, then why did God create a place called hell.
The case for universalism has not been proven and therefore does not warrant belief.
