If Yahweh is just, His "punishment" will fit the crime and the length of time spent in hell will be variable. The most guilty will "suffer" the most, the longest and the hardest.
This teaching fits the Biblical facts and purposes of Yahweh.
If "hell" is a period of purification that "burns out" the impurities, those with the most impurities would take the longest and would "suffer" according to their crimes.
Some people object to the thought that salvation is for ALL. They are like the brother of the prodigal son, who resented his father welcoming back the lost son and restoring him to his former position.
This resentment is no proof that our Father is not able to save ALL. It is only proof that they lack the love of Yahweh.
They probably admit that the Father is Loving and omnipotent, but doubt His ability (or willingness) to save.
What most people fail to perceive is that ALL have sinned (Romans 3:12,23), ALL will be purified by fire (Mark 9:49, 1 Corinthians 3:13), Yahweh is FIRE that purifies (Isaiah 66:16, Jeremiah 23:29), Yahushuah, the Messiah came to bring fire to the earth (Luke 12:49), and ALL (after purification) will be saved (Isaiah 29:24, Isaiah 40:5, Jeremiah 31:34, Luke 3:6, Acts 3:21 Romans 14:11, 1 Corinthians 15:22, Philippians 2:10-11, 1 Timothy 2:3,4).
But, what about "freewill"? What freewill? There are 17 Biblical references in the KJV to "freewill", ALL are regarding offerings. There are 21 references to "choice", ALL refer to choice as "best" (as in "choice" cut of meat), not the ability to choose. See Predestination - The Myth of Freewill.
The will of Yahweh is more powerful than the ignorant will of men. It is Yahweh's will to save ALL. (Isaiah 25:6-10,
Isaiah 40:26, Isaiah 43:5-9, Isaiah 45:22-24, Isaiah 46:10, Isaiah 54:7, Isaiah 60:21, Ezekiel 33:11, Matthew 18:11, John 3:17, John 6:37-47, John 12:32, Romans 8:20-32, 2 Corinthians 5:15, Galatians 3:8, Ephesians 1:9-11, Ephesians 2:10, Colossians 1:15-20, 2 Timothy 1:9, 2 Peter 3:9,15, 1 John 2:2, 1 John 4:14, Revelation 4:11,Revelation 15:4).
The lake of fire is the treading of the winepress is the judgment:
For we must all appear before the judgment seat of the Messiah; that every one may receive the things done in his body, according to that he hath done, whether it be good or bad. 2 Corinthians 5:10
What is Yahweh's Fire? It is His Word. He will open His mouth and reveal ALL - all truth, all love and all sins. This will bring guilt and condemnation on the wicked:
A man that is an heretick after the first and second admonition reject; Knowing that he that is such is subverted, and sinneth, being condemned of himself. Titus 3:10-11
Those with tender hearts will immediately confess, be purified, and enter the open gates of the Holy City. Those with hardened hearts will fight their conscience, but eventually ALL will confess.
That at the name of Yahushua every knee should bow, of things in heaven, and things in earth, and things under the earth; And that every tongue should confess that Yahushua the Messiah is Master, to the glory of יהוה [Yahweh, our god] the Father. Philippians 2:10-11
Whoever confesses that Yahushua is the Son of YHWH, YHWH abides in him, and he in YHWH. 1 John 4:15
That He may be "ALL IN ALL"
And when all things shall be subdued unto him, then shall the Son also himself be subject unto him that put all things under him, that יהוה may be ALL IN ALL. 1 Corinthians 15:28
