Jeremiah 32:27

You all get so hung up on this free will thing? If Satan has the power to deceive people and by their own free will choose to follow him, then God surely has the power to attract people by His love to follow Him by their own free will. Don't worry, God won't make anyone a "robot". He will however continue to love them, guide them, teach them, correct them, even "hand them over to the tormentors UNTIL they have paid the last penny'.
But anyway, Here are some verses I take as showing God as the Savior of all (not a potential savior of some).

John 1:7-9, 29, 3:17, 4:42, 6:51, 12:32, 47, 17:2-4
Acts 3:21, 10:34
Psalms 1:6, 25:8, 94:10, 22:27-29, 107, 119:71, 64:7-9, 65:2-3, 139:8, 136, 106:48, 10:15, 59:10-13

My favorite though is Genesis 1:31, "Behold! Very good!" God at the end of His creating He declares it very good. And then the next chapter begins with Him resting in eternity (no evening and morning). My question is: is God finished creating? Nope! Not yet...Jesus said in john 5:17, "My Father is STILL working...". God is still creating to this day, new hearts, new souls, and one day a new heaven and new earth! Only then will He truely be able to rest when all things are subdue to him (Phil 3:21) and He will be all in all (1 Cor 15:19-28). God is the creator (the cause) of everything (Is 45:7). In Exodus 21: 33-34, 22:5-6, God tells us that if one is the cause of something that leads to the destruction of something else, then he must "make good" (restitution). Well, in the garden God surely dug a pit and did not cover it up, in fact He even hired a tempter to lure us in. All of us have fallen into that pit and are all dead ox's until God purchases (buys back) all that was lost. And this is why Jesus was sent, to "save that which was lost". All things have been handed over to Christ, and Jesus said "all that God has given me I will lose none." The will of God is for all to be saved, Jesus always does the will of the God. Jesus has and will accomplish His mission: Save the World!
the fact is: if the will of God is for everyone to be saved, but Jesus doesn't save everyone, then He failed to do the will of God. But this can't be true, because Jesus always accomplishes the will of God. I'm afraid there will be a lot of "older brothers" (Luke 15) in heaven when God accepts all those who waisted their lives in sin. They will stand outside pouting and the father will plead with them, "come in, its is good we celebrate, once they were lost but now are found. Why are you upset? All I have is yours"

Just these three scriptures are holding you back? Meditate on those verses I posted above...if you don't want to believe that God will restore the universe to perfection, then you never will. I can't move your spirit, only God can do that. If it comforts you to think of everlasting torture than knowing other wise will not.
I am not a universalist, most of them don't believe in sin, punishment, or hell. I believe sin is deadly, punishment is correctional, and hell us real, just not eternal. Study the Greek word for eternal, it might surprise you.

As for those three scriptures...
Rev 20, ain't the end of the book.
Matt 25:46 (EBR), "and these will go into age-abiding correction, but the righteous into life age-abiding."
Mark 3:29, I believe only believers can "speak against" the Holy Spirit. And if they do its an age-abiding sin, they will not be forgiven in the next age (the 1,000 year reign with Christ), but will have to wait for the second resurrection (see Luke 12 and Rev 20).

Jesus talked a lot about "hell" and the punishment that is to come in the next age. And there is, and not only to those wicked non-christians, but "judgement comes to the house of God first" (I believe you will find that in the letters of Peter). What you are not ggrasping is that there are age's' to come, not only one. Jesus spoke (mostly) about the age to come (millennium), also, Gods judgement is ALWAYS correctional, God does not just "endlessly" torture for the sake of torture? Jesus came to show us who the Fatherwas, Jesus forgave his enemies. Jesus is nonviolent! Burning people alive is very violent. It is not in Gods character, people who think God tortures people, do NOT know God. Fire in the Bible is a refining process, its outcome is always good, God is found in the fire in Exodus, Jesus baptizes with fire, and the Holy Spirit is a flame of fire.

No worries, I get pretty fired up too sometimes. Look up what's called "ultimate reconciliation" or "universal restoration" or even "christian universalism", these all are very different from the "unitarian" type "anything goes" theology where "all paths lead to the same place."
Jesus is the only way, and the way is narrow. However, God will create all things new and wipe all tears away. This doesn't mean everyone enjoys the same rewards, but like Paul says in 1 Cor 15, as the lights in the heavens all have different glories, so will people. Some will shine as bright as the sun, while others will shine like Pluto...
