Interesting that so many on this thread take to arguing against others who differ in view or opinion, in order to try and elevate their own view or opinion as truth...
There are many ways to look at many different scriptures. Depending on where you are from, what cultural, experiential, educational, emotional background you come from, you may take different things from different verses.
I find it interesting that so many Scriptures, that we create whole doctrines from, were written as 'mysteries'... maybe we are not supposed to, or never will be able to fully understand them while we are living this part of our lives.
I think if God had wanted us to understand everything, He would have enabled us to..!
So much about even the opening question of this thread can be interpreted in so many different way.
For example, what you see as 'universalism' may be different to how I or another see it. After all, it is a doctrine...
This doctrine / concept itself is built upon our limited understanding of so many other situations, phrases, words that are again, doctrines themselves.
Before anyone gets offended by this, please first look at how the early Scriptures were written, what culture they were written into (which gives insight into how they were written!), what was going on physically in the world at the time (which bares relevance to the approach of the author who's goal was to make a certain people understand) and so on... our understanding is based on our culture and our interpretation.
As well educated as we may be, we make mistakes.
Where mysteries are involved, we can make huge mistakes and assumptions!
Take for example, the use of words such as Heaven, Hell, Salvation, Eternity, Worship, Truth, Redemption... right there you have a list of words that we have coined to fit our modern understanding. Most of these, in the original scriptures were not words that were used, and those that were, were not used in situations that we would use them today.
Be slow to judge others and lean on our own understanding. That's a sure recipe for pride to lead us to fall...
Peace.
