I've been listening for a while now to the Rethinking Hell podcast, run by Chris Date and Dr. Glenn Peoples and some others, trying to learn as much as I can. While I find their insights a welcome relief from the insanity of the Eternal Conscious Torment doctrine, at the end of the day Conditionalism/Annihilationism is still depressing.
Paul said that God is the Savior of all people, especially (not 'particularly') of those who believe (1 Tim. 4:10). Paul also said that at the name of Jesus every knee would bow and every tongue confess that Jesus Christ is Lord (Philippians 2:11). And this: "no man can say that Jesus is the Lord, but by the Holy Ghost." (1 Cor 12:3). He also said that through Jesus God would "reconcile to himself all things, whether on earth or in heaven, making peace by the blood of his cross." (Col 1:20). How about Romans 5:18: "even so by the righteousness of one the free gift came upon all men unto justification of life."
John said "And he is the propitiation for our sins: and not for ours only, but also for the sins of the whole world." (1 John 2:2).
The gates of the New Jerusalem are always open and the invitation is given out to those who are thirsty to come and drink from the water of the river of life (Rev. 22:17).
