We are very much alike Wormwood, we just happen to disagree. Maybe we can start over and examine one verse at a time. I have, in the past, changed my views and am willing to do so now (if moved by the Spirit).
Jesus holds the title of "Savior of the World". John the Baptist (greatest among prophets) proclaims "Behold! Jesus, the Savior (redeemer) of the World (kosmos)!" Paul, apostle to the Gentiles, says "He is the Savior of all men."
Thesestatements, to me, do not reflect any doubt. Maybe he could save? He might be savior, or if the World thinks he is savior, or the lamb could take away the sin of the world. I don't see any doubt. I see nothing but a factual statement that Jesus Christ is the Savior (and I will go so far as to say not just for man, or some men, but in fact the redeemer of the universe, all of creation being restored by the work of Christ. Is he not the potter? To tell you the truth, the big problem I have with an eternal/everlasting hell, is that it would keep sin, pain, evil, hatred toward God, filthy lusts, preserving all these like canned green beans on the shelf, only containing sin but never destroying it. I see Satan the victor in that, not Christ?
From the first pages of the bible to the last page of the bible, scripture shows a God who will not keep his creation forever in sin. Genesis 3:22, God cast out man from the garden, removing the tree of life. Judgment is set: Death! The wages of sin is death. Price paid. Justice is met. But why did God take away the tree of life? Mercy! God said, lest they live forever...God is too loving and merciful to allow His creation to live forever in a state of sin, pain and regret. But that is exactly what the church today teaches hell is: a state of sin, pain and regret where one lives forever. Totally contradicting Gods judgment and character in this passage. Skip 1,000 pages and we come to the end of the book. Where we see "all things" created new and no more tears, the old ways are gone. We see in Revelation 22:2, the tree of life reintroduced, and its leaves are for the healing of the nations. In Rev 21:25, the gates of heaven are never shut, and in Rev 22:15, we see all those who were cast into the lake of fire standing outside the gates, and in Rev 22:17, they are being invited in to take the water of life. We see Gods grace, His love, and His patience towards His creation, the gospel never ceasing to be preached until all those standing outside, who were cast out and judged, come in and be restored. Which will fulfill so many scriptures like Isaiah 45:23, and Psalms 65:2-3, and Phil 2:9-11, and Luke 3:6, and so many more....
