If you desire to know that your understanding of Yeshua is the true Yeshua then simply apply Torah to your understanding of his teachings. Does your understanding of his teachings comply with Torah? If so then perhaps you have the true Yeshua but if not then perhaps you have learned a false version of Yeshua. One very prominent passage, which we know concerns Yeshua according to Luke quoting Peter in the book of Acts, is found in Deuteronomy. I will quote the KJV simply because it is the most widely acknowledged:
Acts 3:19-23 KJV
19 Repent ye therefore, and be converted, that your sins may be blotted out, when the times of refreshing shall come from the presence of the Lord;
20 And he shall send Jesus Christ, which before was preached unto you:
21 Whom the heaven must receive until the times of restitution of all things, which God hath spoken by the mouth of all his holy prophets since the world began.
22 For Moses truly said unto the fathers, A prophet shall the Lord your God raise up unto you of your brethren, like unto me; him shall ye hear in all things whatsoever he shall say unto you.
23 And it shall come to pass, that every soul, which will not hear that prophet, shall be destroyed from among the people.
Acts 3:22-23 is clearly from the following passage but look at the wider context:
Deuteronomy 18:13-22 KJV
13 Thou shalt be perfect with the LORD thy God.
14 For these nations, which thou shalt possess, hearkened unto observers of times, and unto diviners: but as for thee, the LORD thy God hath not suffered thee so to do.
15 The LORD thy God will raise up unto thee a Prophet from the midst of thee, of thy brethren, like unto me; unto him ye shall hearken;
16 According to all that thou desiredst of the LORD thy God in Horeb in the day of the assembly, saying, Let me not hear again the voice of the LORD my God, neither let me see this great fire any more, that I die not.
17 And the LORD said unto me, They have well spoken that which they have spoken.
18 I will raise them up a Prophet from among their brethren, like unto thee, and will put my words in his mouth; and he shall speak unto them all that I shall command him.
19 And it shall come to pass, that whosoever will not hearken unto my words which he shall speak in my name, I will require it of him.
20 But the prophet, which shall presume to speak a word in my name, which I have not commanded him to speak, or that shall speak in the name of other gods, even that prophet shall die.
21 And if thou say in thine heart, How shall we know the word which the LORD hath not spoken?
22 When a prophet speaketh in the name of the LORD, if the thing follow not, nor come to pass, that is the thing which the LORD hath not spoken, but the prophet hath spoken it presumptuously: thou shalt not be afraid of him.
So then, the things Yeshua foretold; did they come to pass or not? If not then we are not to heed or fear that Prophet; this includes passages such as the Olivet Discourse, Matthew 24-26, Mark 13, and any other statements that are understood to have been prophetic utterances. So the question then becomes, how long is long enough to wait, to see if what the Prophet said has come to pass? How long can I wait if my lifespan is no more than seventy years? Can I wait a hundred years and reasonably expect to see what he said come to pass? Can I wait two thousand years to see if what he said comes to pass? If one is realistic about these things then the same should have no problem understanding that no one in the first century expected to wait two thousand years for the words of Messiah to come to pass. They either came to pass in their own lifetimes or we are not to heed or fear that Prophet according to what is written in the Torah quoted herein above. What then does this mean for
your version of Messiah? Do you have the correct Messiah according to what is written in the Torah? Did the words he spoke come to pass or not? The same goes for the author of the Apocalypse and any other writings deemed to have been prophetic including certain statements from Paul. Force your own doctrine to comply with Torah first and the only viable outcome will be that indeed the words of Messiah Yeshua came to pass. However Yeshua said that his words shall never pass away; so they are Spirit, and they apply to every disciple who decides to follow him. Therefore his words must also be fulfilled in you, and not one iota, jot, or little horn, shall pass from the Law till all of it be accomplished, and your "heavens" and your "earth" pass away, and the times of refreshing have come.
