Mark 11:12-14 (NIV)
12 The next day as they were leaving Bethany, Jesus was hungry. 13 Seeing in the distance a fig tree in leaf, he went to find out if it had any fruit. When he reached it, he found nothing but leaves, because it was not the season for figs. 14 Then he said to the tree, May no one ever eat fruit from you again. And his disciples heard him say it.
Matthew 21:18-22 (NIV)
18 Early in the morning, as Jesus was on his way back to the city, he was hungry. 19 Seeing a fig tree by the road, he went up to it but found nothing on it except leaves. Then he said to it, May you never bear fruit again! Immediately the tree withered.
20 When the disciples saw this, they were amazed. How did the fig tree wither so quickly? they asked.
21 Jesus replied, Truly I tell you, if you have faith and do not doubt, not only can you do what was done to the fig tree, but also you can say to this mountain, Go, throw yourself into the sea, and it will be done. 22 If you believe, you will receive whatever you ask for in prayer.
I believe this scripture is talking about false prophets. I think it cant be talking about the Nation of Israel because over and over in the bible you read passages about how God promises to save Israel. Israel may be punished by God, but they are never forsaken. God always promises that he would save them.
I think the key to understanding this is:
Matthew 7:15-20 (NIV)
15 Watch out for false prophets. They come to you in sheeps clothing, but inwardly they are ferocious wolves. 16 By their fruit you will recognize them. Do people pick grapes from thornbushes, or figs from thistles? 17 Likewise, every good tree bears good fruit, but a bad tree bears bad fruit. 18 A good tree cannot bear bad fruit, and a bad tree cannot bear good fruit. 19 Every tree that does not bear good fruit is cut down and thrown into the fire. 20 Thus, by their fruit you will recognize them.
Jesus is talking about False Prophets in Matthew 7:15-20 and says by their fruit you will recognize them. Good teachers (righteous) bear good fruit (The fruit are their students). Likewise Bad (false) teachers yield bad fruit. A student will only turn out the way their teacher guides them. A false prophet will teach untruth to their students and as such lead them astray.
Which is why Jesus says to the false prophet May no one ever eat fruit from you again. Meaning may you never teach lies and untruth again and thus yield bad fruit (bad students/bad disciples).
Then in Matthew 7:19 (NIV) Jesus says that the False Prophets will be thrown into the fire, meaning hell.
I think Mark 11:12-12 is explained this way:
13 Seeing in the distance a fig tree in leaf, he went to find out if it had any fruit. (Meaning Jesus saw many prophets at his time, so he went to investigate their teaching)
When he reached it, he found nothing but leaves, because it was not the season for figs
(meaning upon listening to the teaching of these prophets at the time he found empty teaching, not bearing any good results. They were teaching untruth, so their students were doing the same things they were, yielding no good fruit)
because it was not the season for figs (So at the time of Jesus ministry he was to be the only one teaching! I mean think about it. God wanted people to listen to Jesus only, so God would not have sent another prophet at that time to also be teaching at the same time as Jesus. It was not the time for prophets. It was the time for Jesus alone. The prophets were sent BEFORE Jesus to prepare his way, like John the Baptist. All the Prophets pointed to Jesus. So this was NOT the time for Prophets.)
These false prophets were teaching untruth.
You're not alone about thinking about all Israel being saved meaning literal Israel. Do you recall at Matthew [23v38] that Jesus said the Jewish religious [house of worship] temple would be left desolate or abandoned ?
The religious leaders were held bloodguilty in Jesus eyes according to verse 35 all the way back to Abel [Rev 18v24]
Since Pentecost the Israel of God [Gal 6v16;Acts 15v14] was No longer the literal nation of Israel, but now the Christian congregation would be the Israel of God or the all spiritual Israel would be saved.
Please notice [1st Peter 2 vs4,5,9]
There it is described as a holy nation a spiritual religious house of worship with now spiritual sacrifices. Whereas the Israel of today exists as a national group.
At Galatians [4v26] the Jerusalem mentioned there is not earthly Jerusalem but now heavenly Jerusalem or Jerusalem above.
What Scripture put literal fire in the biblical hell [sheol] ?
Was Jesus in fire while he was in hell ? ______Acts 2vs27,31,32; Psalm 16v10
Before Jesus died he likened the Bible's hell [sheol] to being in an unconscious sleep-like state at John 11vs11-14.
Jesus would have gotten that sleeping-state idea from the Hebrew OT Scriptures such as: Psalms 6v5; 13v3; 115v17; 146v4
Besides King Solomon, known for his God-given wisdom, wrote at
Ecclesiastes [9v5] that the dead are Not conscious of anything.
So, the biblical hell [sheol] is just the common grave of dead mankind.
The biblical hell is temporary according to Revelation [20vs13,14]
After everybody in the Bible's hell is 'delivered up [resurrected]
then emptied-out hell is cast into second death.
Isn't the lake of fire the second death?.
The lake of fire aka second death then is not the Bible's hell but the English word hellfire comes from the word Gehenna.
Gehenna was just a garbage pit where things were destroyed not kept burning forever.
