You are all dealing with what I call being "spiritually" born again. What Yeshua was talking about in John 3, however, is being "literally" born again. Here is my take on that.
"Jesus (Yeshua) answered and said unto him, 'Verily, verily, I say unto thee, Except a man be born again, he cannot see the kingdom of Elohim."
Yeshua spoke these words to Nicodemus, a Pharisee and ruler of the Jews. By Nicodemus' reply it is obvious that he misunderstood Yeshua in that he was thinking an adult could somehow enter his mother's womb a second time and be born a second time.
Yeshua then clarifies further in verse 5;
"Jesus (Yeshua) answered, 'Verily, verily, I say unto thee, Except a man be born of water and of the Spirit, he cannot enter into the kingdom of God."
Yeshua is explaining only one aspect of being born again, the literal meaning. There is a second aspect, the spiritual meaning, which will be dealt with in another post if you would like my take on that as well. To be "born of water" refers to one's physical birth. The unborn child is encased in "water" for the majority of his life in the womb. Once that encasement breaks and the "water" is released the birth begins. Yeshua was responding to Nicodemus' question about entering his mother's womb a second time. So, in essence, Yeshua was saying, "Except a man be born of the womb and of the Spirit . . ."
Many have concluded that Yeshua was referring to baptism in water and the baptism of the Holy Spirit. Based on the context that follows, that is not true. Verse 6 reads,
"That which is born of flesh is flesh; and that which is born of the Spirit is spirit."
Yeshua is drawing a parallel to what he just said in verse 5. To be "born of the flesh" equals to be "born of water." When a person is born of water he is born a flesh and blood being. However, when a person is born of the Spirit he is spirit. He becomes a spirit being. This can only happen to a person upon his resurrection from the dead. That is what happened to our Savior Yeshua upon his resurrection from the dead. Psalm 2:7 reads,
"I will declare the decree: The LORD (Yahweh) hath said unto me, Thou art my Son; this day have I begotten thee."
Its fulfillment is found is found in Acts 13:33;
"God has fulfilled the same unto us their children, in that he has raised up Jesus (Yeshua) again; as it is also written in the second Psalm, Thou art my Son, this day have I begotten thee."
Yeshua's resurrection from the dead was the point in time that he was "begotten" or "born again." He was "born of the flesh" or "born of water" when his mother Mary gave birth to him. "And the Word was made flesh and dwelt among us. . ." (John 1:14)
Yeshua is said to be the "firstborn from the dead" (Col 1:18). He was the first person to be resurrected unto eternal life or the first to be "born" via resurrection. Romans 8:29 says,
"For whom He did foreknow, He also did predestinate to be conformed to the image of His Son, that he might be the firstborn among many brethren."
Therefore, all those that believe in the Son (his brethren) will also be resurrected or literally born again as he was.
The Apostle Paul wrote,
"It is sown a natural body; it is raised a spiritual body. There is a natural body and there is a spiritual body" (1 Corinthians 15:44).
The "natural body" means our flesh and blood body that was born of water or of the flesh. The "spiritual body" means the new body that is reserved in heaven for each saint that will be resurrected. In 2 Corinthians 5:1-4, Paul speaks of this spiritual body as our future "house."
"For we know that if our earthly house of this tabernacle were dissolved, we have a building of God, a house not made with hands, eternal in the heavens. For in this we groan, earnestly desiring to be clothed upon with our house which is from heaven."
Notice, also, in 1 Corinthians 15:44, that Paul says the natural body is "sown." Just as a seed is sown in the ground and gives birth to a new plant, so must we be sown in death before we are literally born again at our resurrection as spirit beings. We will literally experience a new birth into a different kind of being, one that is not subject to sickness or death or hindered by the physical barriers of life in the flesh such as walls. This latter ability of a spirit being is very important in understanding what Yeshua meant in John 3:8.
"The wind bloweth where it listeth, and thou hearest the sound thereof, but canst not tell whence it cometh, and whither it goeth: so is every one that is born of the Spirit."
Yeshua is saying, if you are a person who is born of the Spirit, you will be able to come and go without detection because spirit beings are invisible. We all know that angels, who are spirit beings, are invisible until made manifest to human eyes for some reason as was the case with Elisha and his servant in 2 Kings 6:17. The same is true of Yeshua now that he has been resurrected or born again, born of the Spirit. In Luke 24:31, Yeshua vanished out of the sight of Cleopas and his traveling companion. Later, in Luke 24:36, Yeshua suddenly appeared in the midst of his disciples as they spoke to one another. His appearance was so sudden and unexpected that they thought they were seeing a spirit. John 20:19 tells on that occasion the disciples were hiding in a room in fear with the door shut. It is not too great an assumption to believe the door was locked as well, yet Yeshua, as a spirit being, was not hindered by the physical world. He passed through the door or wall, undetected as the wind, to speak to his disciples.
All this simply confirms what Paul said in 1 Corinthians 15:50;
"Now this I say, brethren, that flesh and blood cannot inherit the kingdom of God; neither doth corruption inherit incorruption."
This is another way of saying, " Except a man be born again, he cannot see the kingdom of God" and "Except a man be born of water and of the Spirit, he cannot enter into the kingdom of God." The literal kingdom of Yahweh is closed to all that are flesh and blood. Its doors will open when the flesh is made spirit at a person's resurrection. When the earth gives birth to a dead saint their entrance into the kingdom is permitted.
What about this concept of the earth giving birth? Is it Scriptural? Most certainly. Consider Isaiah 26:19;
"Thy dead men shall live, together with my dead body shall they arise. Awake and sing, ye that dwell in the dust: for thy dew is as the dew of herbs, and the earth shall cast out the dead."
It is the earth that is going to "cast out" the dead via resurrection when dead bodies shall arise. "Cast out" is #5307 in Strong's Concordance. A root of it is #5309 which means an "untimely birth." Consider, also, Isaiah 66:8;
"Who hath heard such a thing? Who hath seen such things? Shall the earth be made to bring forth in one day? or shall a nation be born at once? for as soon as Zion travailed she brought forth her children."
Zion will give birth to her "children," but it is the earth that is actually made to "bring forth" or give birth to these children. This refers to the resurrection of believers. The resurrection of Yeshua is referred to in verse 7.
In John 3:9, Nicodemus says, "How can these things be?" Yeshua replies, "Art thou a master [teacher] of Israel and knowest not these things?" In other words, Nicodemus should have known from the Old Testament what Yeshua was talking about. Nowhere in the Old Testament, that I am aware of, is the concept of being born again while in the flesh taught. However, the resurrection of the dead is taught and that is what Yeshua was referring to by being "born again" and "born of the Spirit."
What Yeshua taught in John 3:3-12 is the literal act of being born again. There is also a spiritual aspect of being born again which is far more important. Without being born again spiritually we cannot expect to be born again literally at our resurrection.
