Im glad you mentioned the fig tree. Speaking of what one can or cannot know, it is an example of something which requires spiritual perception.
The fig tree is a metaphor for Israel which is a type for the Christian walk. In the firstripe Israel was full of promise, but then she went astray:
For verily I say unto you, That whosoever shall say unto this mountain, Be thou removed, and be thou cast into the sea; and shall not doubt in his heart, but shall believe that those things which he saith shall come to pass; he shall have whatsoever he saith.
Therefore I say unto you, What things soever ye desire, when ye pray, believe that ye receive [them], and ye shall have [them]. And when ye stand praying, forgive, if ye have ought against any: that your Father also which is in heaven may forgive you your trespasses. But if ye do not forgive, neither will your Father which is in heaven forgive your trespasses. Mark 11:20-26
Nathanael answered and saith unto him, Rabbi, thou art the Son of God; thou art the King of Israel. Jesus answered and said unto him, Because I said unto thee, I saw thee under the fig tree, believest thou? thou shalt see greater things than these. And he saith unto him, Verily, verily, I say unto you, Hereafter ye shall see heaven open, and the angels of God ascending and descending upon the Son of man. - John 1:47-51
Mark wrote:
... And seeing a fig tree afar off having leaves, he came, if haply he might find any thing thereon. He did not say it was a charade to provide a spiritual lesson. I believe Mark.
Your view agrees with most of the commentaries. I think the commentaries are mistaken.
Men come to the Bible assuming they know what it teaches, and when they find something that doesn't quite agree with what they expect, they "interpret" it to mean what they want. I only take the plain meaning where it is clear.
The only lesson Jesus himself made from this incident is the lesson on prayer. That's sufficient for me.
People have a very strange Idea that Jesus was not really a human being like other human beings. The Bible says he "became" flesh and blood, that is, a human being. He was not God in a man, He was God become a man, completely a man. Do you suppose Jesus did not have to look where he was walking, find his sandals, and look when he was pouring wine? If he was really a man He would have to, and if He was really a man, he would not know what was on a fig tree until He looked.
