This is a fundamental question that must be answered by every person who is in search of the truth. The correct understanding of the nature of Christ is needed to comprehend the most important aspect of His mission as the Messiah of YHWH.

Namely, how did he reverse the curse of sin and death that we inherited from Adam? 

There is a hidden element within those questions that it is not generally known. Sometimes our personal understanding of the scriptures is derived mostly from our upbringing and formal training. Whether we care to admit it or not, Christianity became an institution complete with customs and traditions that many follow without question. We tend to trust our leaders for the answers. However, even if their teaching is of sound doctrine, the scriptures are quite plain in saying that our search for the truth must be advanced through a personal study. The truth is "the treasure" buried in a field, and the scriptures are the treasure map. Studying the map is the only way to develop a close relationship with our Creator. There are many voices out there, but only God (YHWH) can give us confirmation of the truth. The hidden element I referred to is not a new doctrine. As you will see, it is has always been there waiting for you to discover it, just as I have. 

I asked my Father to explain to me the hidden wisdom behind the Book of Revelation. His answer was simple; first read and understand the story of Creation. What happens in the end of days, is the restoration of what was started in the beginning. We will return to the Garden of Eden. Anyone who desires to understand the fulfillment of all things, must understand what took place in the first three chapters of the Book of Genesis.

When Adam gave his authority over to Satan, what actually occurred was a legal transfer of power. After which, Satan constructed what can only be called a counterfeit reality. It is a counterfeit because it exists in opposition to the Creator's will. It is not a false reality; whatever happens here affects all of creation, in a real way. Yet, it is not the reality our Creator planned for us in the beginning. If it were, then Christ would not have prayed, "your will be done on earth as it is in heaven," obviously meaning that the Father's will is not done on earth.

Within the parameters of his counterfeit reality, the master deceiver has sent out many false teachers and prophets to confuse the people. They erect fences and walls around the minds of their victims. They propagate myths, fables, and stories; and create false interpretations of scripture that water down or eliminate the truth. They may even appear to be sincere followers of YHWH, but they have aided the enemy in this age old war. A war that is fought to control your thoughts and your mind, and ultimately your body. The weapons used in this warfare are words. Be not mistaken, there is real power behind the spoken word. We use letters to create words, and we call this exercise, "spell-ing." Even our English word "grammar," which is defined as a set of language rules; comes from the 12th Century French word, "grammoire" (from a Latin root) and means, "Book (or rules) of Magic." But what is a spell? Most people attach a negative connotation to the word, and rightly so. Yet the English word "gospel" is derived by combining the words "good-spell." We can use a "gospel" to proclaim the "good news;" or we can cast a spell through lies and deceit, using words to create suspicion, doubt, fear, and unbelief.

Consider the Hebrew word "nachash," [pronounced, naw-khawsh] which is translated as "serpent," and is used to describe the one who was in the beginning, in the Garden of Eden. This word can be a noun or a proper name. As a noun it means enchanter, to whisper a spell (or spell caster), magician, and prognosticator.  

Each one of those definitions involves manipulation through the use of words. This is exactly what happened in the Garden of Eden. In Old Testament manuscripts, this very same "nachash" receives the definite article "the," which is written in Hebrew as "haNachash," making this word a personal name. It is haNachash (Satan, the serpent) who gently persuaded Adam's wife, with carefully chosen words, to consider her "other options." He even had a prognosis for Eve, saying to her, if she ate the fruit of knowing good and evil, she would "not surely die." 

I don't believe this was the first time or the only time that Eve spoke with haNachash. His plan for Eve's downfall was a work in progress. It began when he challenged Eve's perception of the truth. He did this to lay the foundation for his counterfeit reality. Satan had to convert words into actions, but the scriptures are clear to point out that Satan could not have overpowered Adam and Eve by force. He had to accomplish this takeover through manipulation and deceit.

The "binding" being referred to here can be literal, or it can be figurative in the sense of being "spellbound."  A condition that exists when words are used to entice and fascinate someone, in order to solicit a response. The so called "victim" (or victims) have participated voluntarily, and in a real way, left themselves open to this manipulation. This is how Satan was able to usurp Adam's authority. Adam was the strong man, and Satan spoiled his house.

For this reason we are instructed to cast down imaginations that oppose the truth before they become strongholds that must be - pulled down. They are restraints that hinder our spiritual understanding. They are invisible walls that are just as solid as concrete.

In these last days, as the knowledge of God (YHWH) and his truth increases (in fulfillment of prophecy) the counterfeit reality will crumble. But before it completely falls, there will be one more challenge which will be the greatest test of all. Medical science, specifically biotechnology (with the assistance of nano-technology) will reconstruct the gene sequence that enables immortal life. God (YHWH) will allow this proprietary information to be used to bring about the strong delusion spoken of in 2 Thessalonians. This delusion will be made manifest so that the wicked;

That lie will amount to this; 

the curse of sin and death has been reversed.

The Creator's Holy image, which he imprinted on our bodies and later called "His temple;" will be desolated (made barren) by the abomination (moral revulsion) known as the Son of Perdition (the anti-Christ). At the heart of this delusion will be his ability to impart this immortality to others;

for a price. 

The sin cursed and mortal body of flesh, will be synthetically converted by means of a genetic therapy into an immortal life. Man, who has been cut off from the tree of life since the Garden of Eden, will climb in over the back wall - just as Christ prophesied. 
The immortal life therapy will enable the lame to walk, the blind will see, the mute will speak, and those maimed will be made whole.   

And great multitudes came unto him, having with them those that were lame, blind, dumb, maimed, and many others, and cast them down at Jesus' (Yhwhswa) feet; and he healed them:

This therapy will duplicate the work which was done by the true Messiah.
There will be no sickness or death. It will even reverse the aging process.
The person who brings all of this to the people of earth - will be nothing less than a Messiah. Just as it happened almost 2000 years ago, great multitudes will come unto him, the anti-Christ, and glorify the God of Israel, and shall wonder over his work.
Only this "messiah" will be the Son of Perdition, and the god who sent him is the dragon of Revelation 13:4.

It will be a beautiful delusion.

Unlike any other ever seen before on earth.
