Universalism has many shapes and forms. The most liberal doubt the truth of the Bible in one way or another, instead choosing to rely on the kind of God they feel comfortable with.
There is however a variety of universalism that claims to be Biblical (although normally not dispensational). When there is a claim to being Biblical, then there is common ground to work with.
This lesson goes through doctrines found in the Bible that make it near impossible for an universalist to be a Bible believer. The universalist always sees a hope for everyone to reconcile, the Bible is not as optimistic toward man.
