You said, " No one would come up with ' enabling grace , irresistible/ previenient Or any other add on ,from just reading the bible"
That is not true at all. A complete and total falsehood on your part sir.
To begin with, it is implied in Eph. 2:4,5: ... "even when we were dead through our trespasses, made us alive together with Christ (by grace have ye been saved"). Made alive because we were dead. That which is DEAD cannot make itself ALIVE. This would be a foolish notion. If one believes contrary to this, then ones understanding and logic is as flawed as Nicodemus' was. To proceed from a spiritually DEAD state, to a spiritually ALIVE state, would take an "enabling grace". That which is spiritually dead cannot understand spiritual things, even if they have been apart of "religion" for many years. Just like Nicodemus.
If a "dead in spirit sinner", is at the bottom of the pit of destruction and a lifeline is thrown to him, in the person of Jesus Christ, how can he grab it, if he is dead. A dead person cannot SEE are HEAR are physically react to the lifeline. Correct? Or do you have some other meaning for what a dead person can or cannot do?
This I suppose, is why you did not answer my question about John 3:3-10. I will. First, let's establish what took place before verse 3.
Nicodemus came to see Jesus at "night" because he did not want his fellow religionist seeing him talking to Jesus. He knew Jesus as a Rabbi, Teacher and that God was with Him, however he did not see him as Savior, The God-Man or The Son. Why? He was spiritually dead. Now this sets the context of our Lord's words.
This clearly teaches the need for an enabling form of Grace:
John 3:3 Jesus answered and said unto him, Verily, verily, I say unto thee, Except one be born anew, he cannot see the kingdom of God.
Here Jesus speaks in Kingdom language but to understand Jesus as Savior and gain entrance into the Kingdom of Heaven/of God, the principle is the same.
John 3:4 Nicodemus saith unto him, How can a man be born when he is old? can he enter a second time into his mother's womb, and be born?
Nicodemus expresses his spiritual ignorance.
John 3:5 Jesus answered, Verily, verily, I say unto thee, Except one be born of water and the Spirit, he cannot enter into the kingdom of God.
Jesus repeats this need for a spiritual awakening. Also, in Scripture called the quickening. In Theological circles, called Regeneration.
John 3:6 That which is born of the flesh is flesh; and that which is born of the Spirit is spirit.
Jesus qualifies His announcement, to show that "flesh" cannot give birth to that which is spirit. Only the Holy Spirit can give birth to that which is spirit. By interpretation, only The Holy Spirit, can make one spiritually alive.
John 3:7 Marvel not that I said unto thee, Ye must be born anew.
As Nicodemus was in a spiritually dead state, he was shocked by this proclamation and understood it not. Just as many "religionist" do not today.
John 3:8 The wind is blowing where it will, and thou are hearing the voice thereof, but are not knowing from where it comes, and where it going: so is every one that is born of the Spirit.
Jesus gives an illustration of how the Holy Spirit goes about this work. He goes to those he wills (this would be linked to passages in John Ch. 6 and 10 and 17), the one he is working on hears the voice but cannot tell where He came from or where He is going.
John 3:9 Nicodemus answered and said unto him, How can these things be?
Always the reaction of the spiritually dead individual.
John 3:10 Jesus answered and said unto him, Art thou the teacher of Israel, and are not understanding these things?
Finally, Nicodemus is criticized by Jesus Christ because he is in the position of a teacher but is ignorant of how salvation works.
It is a dangerous thing to be placed as a teacher and be responsible for teaching error. If I am wrong in my teachings and cause others to err, then I will be held accountable. Not in the way of my "position" in Christ but in my "condition" and later, when I stand before Christ for rewards or loss thereof. I take what I say seriously.
Now sir, you seem somewhat learned, so why are you ignoring these things?
The rest of John 3, all they way to verse 21, is a continuation of the conversation Jesus is having with Nicodemus. Let us never forget, Jesus is speaking to a religious teacher who is spiritually unable to comprehend these things.
