Matthew 21:21 (KJV)

Jesus answered and said unto them, Verily I say unto you, If ye have faith, and doubt not, ye shall not only do this [which is done] to the fig tree, but also if ye shall say unto this mountain, Be thou removed, and be thou cast into the sea; it shall be done.

Mark 11:23 (KJV)

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.

Revelation 8:8 (KJV)

And the second angel sounded, and as it were a great mountain burning with fire was cast into the sea: and the third part of the sea became blood;

Revelation 18:21 (KJV)

And a mighty angel took up a stone like a great millstone, and cast [it] into the sea, saying, Thus with violence shall that great city Babylon be thrown down, and shall be found no more at all.

Jesus said that He had overcome the world:

[Jhn 16:29-33 KJV] His disciples said unto him, Lo, now speakest thou plainly, and speakest no proverb. Now are we sure that thou knowest all things, and needest not that any man should ask thee: by this we believe that thou camest forth from God. Jesus answered them, Do ye now believe? Behold, the hour cometh, yea, is now come, that ye shall be scattered, every man to his own, and shall leave me alone: and yet I am not alone, because the Father is with me. These things I have spoken unto you, that in me ye might have peace. In the world ye shall have tribulation: but be of good cheer; I have overcome the world.

Jesus makes certain promises to them that overcome as, or in the like manner, He also overcame:

[1Jo 5:4-5 KJV] 4 For whatsoever is born of God overcometh the world: and this is the victory that overcometh the world, [even] our faith. 5 Who is he that overcometh the world, but he that believeth that Jesus is the Son of God?

[Rev 2:7, 11, 17, 26 KJV] 7 He that hath an ear, let him hear what the Spirit saith unto the churches; To him that overcometh will I give to eat of the tree of life, which is in the midst of the paradise of God. … 11 He that hath an ear, let him hear what the Spirit saith unto the churches; He that overcometh shall not be hurt of the second death. … 17 He that hath an ear, let him hear what the Spirit saith unto the churches; To him that overcometh will I give to eat of the hidden manna, and will give him a white stone, and in the stone a new name written, which no man knoweth saving he that receiveth [it]. … 26 And he that overcometh, and keepeth my works unto the end, to him will I give power over the nations:

[Rev 3:5, 12, 21 KJV] 5 He that overcometh, the same shall be clothed in white raiment; and I will not blot out his name out of the book of life, but I will confess his name before my Father, and before his angels. … 12 Him that overcometh will I make a pillar in the temple of my God, and he shall go no more out: and I will write upon him the name of my God, and the name of the city of my God, [which is] new Jerusalem, which cometh down out of heaven from my God: and [I will write upon him] my new name. … 21 To him that overcometh will I grant to sit with me in my throne, even as I also overcame, and am set down with my Father in his throne.

[Rev 21:7 KJV] 7 He that overcometh shall inherit all things; and I will be his God, and he shall be my son.

I take note that When Jesus proclaimed He had overcome the world, the world itself was largely unchanged. In fact, upon His ascending up, things appeared much as they did before He came. Jesus was not mistaken in saying He had overcome the world. He overcame it in himself, among other things. But it is certain, that the world is presently overcome by Him. Jesus spoke certain things obtainable to he/she who overcomes as He has. Much of this has to do with becoming permanent fixture in the Father’s House (Which Christ is, and them in Him. He is the house of many houses). A part of this overcoming has to do with the revelation of this house, and the rejection of the false. Jesus stood next to that which is widely accepted as “the” temple, and said the words, “destroy this temple and I will build it again in three days”. The resurrection confirmed Jesus’ definition of temple. There is no other. To this day, many “christians” along with others, sit mesmerized with Jerusalem and wait for a “temple”. In like fashion as with His glorification, so the definition of “temple” will be confirmed with His coming and appearance…in His temple. He comes and will be admired and glorified in His saints and in them who have believed (the truth).

When Jesus said, in Matthew 21 and Mark 11, “you shall say to this mountain…”, do not gloss over the word “this”. That word begs the question, what mountain? And it also is in association with the cursing of a fig tree, which soon withered. The fig tree is in scriptures, often symbolic of the Father. The fig is an interesting plant. It is worth studying. Among it’s attributes is the manner in which it forms fruit. And the fig, once formed, blooms inside itself. The flowers are not visible on the outside. Jesus could discern a fig tree that was not what it is represented to be. So, also , Jesus stood before what is accepted as “the” temple, and said if you have faith, you will say to THIS mountain, be removed and cast into the sea”, (and out of your mind and being). This same “temple” had been built on a mountain called “Olives” (symbolic of the Holy Spirit), but even in Solomon’s day, the mount had become so corrupt, it was referred to as the mount of corruption. The over comer will see this arrangement of false temple and father for what it is, and, as Jesus also did when tempted with it, cast it from his/her being and into the sea of raging flesh where it belongs, and wherein it will be judged.

[Mat 4:1-11 KJV] 1 Then was Jesus led up of the Spirit into the wilderness to be tempted of the devil. 2 And when he had fasted forty days and forty nights, he was afterward an hungered. 3 And when the tempter came to him, he said, If thou be the Son of God, command that these stones be made bread. 4 But he answered and said, It is written, Man shall not live by bread alone, but by every word that proceedeth out of the mouth of God. 5 Then the devil taketh him up into the holy city, and setteth him on a pinnacle of the temple, 6 And saith unto him, If thou be the Son of God, cast thyself down: for it is written, He shall give his angels charge concerning thee: and in [their] hands they shall bear thee up, lest at any time thou dash thy foot against a stone. 7 Jesus said unto him, It is written again, Thou shalt not tempt the Lord thy God. 8 Again, the devil taketh him up into an exceeding high mountain, and sheweth him all the kingdoms of the world, and the glory of them; 9 And saith unto him, All these things will I give thee, if thou wilt fall down and worship me. 10 Then saith Jesus unto him, Get thee hence, Satan: for it is written, Thou shalt worship the Lord thy God, and him only shalt thou serve. 11 Then the devil leaveth him, and, behold, angels came and ministered unto him.

With these words, Jesus cast mountain, “temple” and so-called father, from Himself.
