I don't believe mankind as a whole ever needed to be saved in an eternal sense. To me the whole being saved thing was about the Jews back then being saved from the destruction of Jerusalem in AD70 & being "saved" from the curse of the Law, which is being separated from God, not in reality, but in our own mind / perception.
As for us nowadays, it's not a saved or not saved issue... it's again a perception problem. God is at peace with ALL people, just most of them don't realize it yet because religious leaders have not been given a revelation of the true Gospel! Why.... Because as humans we tend to glorify those that we believe. If truth comes from our human teachers, we glorify them, instead of God... so God reveals truths to those who seek Him directly, not those who place their trust in the words of human teachers!
Even now, DO NOT believe what I am saying... ASK God, seek Him and you will be given truths that are hidden from most!
