I've begun the course you've spoken of and have read again the Scripture written by the Holy Spirit through the pen of Mark, starting at chapter 9.
This lead me to look at Scriptures that compare "Wicked People" in Nave's Topical Index:
Compared with » Abominable branches (Isaiah 14:19)
Compared with » Ashes under the feet (Malachi 4:3)
Compared with » Bad fish (Matthew 13:48)
Compared with » Animals (Psalms 49:12; 2 Peter 2:12)
Compared with » Blind people (Zephaniah 1:17; Matthew 15:14)
Compared with » Bronze and iron (Jeremiah 6:28; Ezekiel 22:18)
Compared with » Briers add thorns (Isaiah 55:13; Ezekiel 2:6)
Compared with » The bulls of Bashan (Psalms 22:12)
Compared with » Carcasses trodden underfoot (Isaiah 14:19)
Compared with » Chaff (Job 21:18; Psalms 1:4; Matthew 3:12)
Compared with » Clouds without water (Jude 1:12)
Compared with » Corn (grain) blasted (2 Kings 19:26)
Compared with » Corrupt trees (Luke 6:43)
Compared with » Deaf adders (Psalms 58:4)
Compared with » Dogs (Proverbs 26:11; Matthew 7:6; 2 Peter 2:22)
Compared with » Dross (Psalms 119:119; Ezekiel 22:18,19)
Compared with » Early dew that passes away (Hosea 13:3)
Compared with » Bad figs (Jeremiah 24:8)
Compared with » Fading oaks (Isaiah 1:30)
Compared with » Fiery oven (Psalms 21:9; Hosea 7:4)
Compared with » Fire of thorns (Psalms 118:12)
Compared with » Fools building upon sand (Matthew 7:26)
Compared with » The fuel of fire (Isaiah 9:19)
Compared with » Garden without water (Isaiah 1:30)
Compared with » Goats (Matthew 25:32)
Within the above Scriptures (included here for ease of mouse-hover-reading) are a many that could be studied for their own sake. Psalm 21:9 mentions a fiery oven, where the fire shall consume them. Hosea 7:4 speaks in similar fashion. Ezekiel 22:18 speaks of the "dross of silver" - that which, after the silver has been heated to the melting point, is scooped and cast away, Matthew 3:12 speaks of burning of the chaff, Hosea 13:3 speaks of smoke (where there is smoke, there is fire, right) - but it speaks of smoke out of a chimney, not the fire, but the remainder: smoke. That's nebulous and transient, seen for only a moment as it wisps away.
This concept is re-enforced by references to chaff and wind, by burned branches or dried up plants or ashes or stubble (as in the famous wood, hay and stubble references). Such things bring with them a connotation of impermanence. Now, before we conclude that all such things must be referring to living persons, we also are given reference to them being devoured in the time of His anger, and being destroyed in the Name of the Lord. Isaiah speaks of the time of the wrath of the Lord and the fuel of the fire where no man shall spare his brother (Isa 9:19). In that case, "
they" are the fuel, but there is nothing that I've seen that specifically states they are the only fuel.
It seems that there are many "time clues" contained within these references and that it does deserve more attention than I've given the subject. This conclusion supports Free's allegation that these things are not "black and white," not clear but may be seen in part, not fully revealed (yet). 20/20 vision or hindsight will allow more authoritative statements to be made, but as I've previously confessed, I'm not a Prophet who may discern these future events with that same degree of accuracy.
Still, while following your admonition to go to Mark chapter 9, some things do become more clear. For instance, as you've requested, my thought went to overview of the whole chapter.
- “Truly I tell you, some who are standing here will not taste death before they see that the kingdom of God has come with power.”
- The Transfiguration on the Mountain with three witnesses
- Jesus Heals a Boy Possessed by an Impure Spirit
- Jesus Predicts His Death a Second Time
- Taking the child in his arms, he said to them, “Whoever welcomes one of these little children in my name welcomes me
- "Whoever Is Not Against Us Is for Us" (“For no one who does a miracle in my name can in the next moment say anything bad about me, 40 for whoever is not against us is for us. 41 Truly I tell you, anyone who gives you a cup of water in my name because you belong to the Messiah will certainly not lose their reward.)
- Causing to Stumble
- Mark 9:48 & Isaiah 66:24
- vs 49, "Everyone will be salted with fire." Other ancient authorities either add or subtract "Every sacrifice will be salted with fire."
- Conclusion: "Have salt among yourselves, and be at peace with each other.”
