This thread is terrible. OP, you have not directed it well to achieve what you declared to have set out to do. I want to give you that opportunity. Here is what I think can set you in the right direction:
1. What is spiritual life? It is to be alive to Christ. What is Christ? It (He, a living personality) is the truth and the life.
The first story in the bible is about when man and woman had to choose whether they want this life forever under one condition. We see that they had two options: they could eat from the tree of life and live forever, they could eat from another tree and they would die. Whatever you make of this story in terms of historical accuracy is beside my point. Here we see that the human chose to forsake their right to life, and as a statement of basic human nature when making decisions, it is a fairly accurate picture.
Put this in context of Christ being the truth and the life, we see that the story shows they rejected Christ. Since there is no person who never rejects Christ, we all make the same decision at some point. This is the meaning as I see, of being born again. It means that we are given a new life which is only by accepting Christ (note that I also think this can happen before the person consciously knows that it is Christ they have accepted. It is a change of heart such that they receive what the spirit of Christ tells them. And He will lead them to a knowledge of the truth). This is the act of eating from the tree of life which is in the paradise of God. Do you know what the bible says about that?
Genesis 3:
And the Lord God said, The man has now become like one of us, knowing good and evil.
He must not be allowed to reach out his hand and take also from the tree of life and eat, and live forever.
.. So how is it that Christians can believe such a thing as this:
Very truly I tell you, whoever obeys my word will never see death. (Jesus)
.. So Jesus appears to be using the word death to mean something other than the cessation of the human body's function. In fact, this is clear through that entire dialogue (see John 8).
In that dialogue is also a statement that is directly relevant to your original question, and what I have brought into it with the tree of life and the tree of the knowledge of good and evil. Check this:
Whoever belongs to God hears what God says. The reason you do not hear is that you do not belong to God.
What makes a person not belong to God? It is not through rightful ownership, because if you assume that God is the creator as is claimed in this religion, then everything must belong to Him. Instead the word "belong" in this sentence does not talk about rightful ownership, it talks about allegiance. This is what we see in the story of Genesis chapter 3. The man and woman chose to believe what the serpent told them instead of what God told them. In doing so, they became susceptible to death. Before that time, they had no fear of death. Immediately, they hid from God. And this is what we all do at some point in our life. We hide from God. God is the only one who can give us life, but we choose to hide from Him
So to be born again as I understand it to mean in this spiritual context, is to have that life reinstituted so we can approach God freely and in confidence. But how can we do that if we believe that God will not accept us, that our "best deeds are filthy rags in His sight"? The answer is not to believe that our best deeds are not filthy rags in His sight, because that is distorting a claimed and justifiable truth. Instead, we need to have the confidence that He forgives our mistakes and accepts us. In Christianity, it is taught that Jesus is the mediator between God and man. I will have to think more about how that works, I don't fully understand it at this time. But what I do understand is that God is happy for Jesus to be responsible for His sheep. Jesus' sheep tend to follow Him because they love to obey Him. I think this probably contributes somewhat to God's trust in Jesus as our mediator.
My hope is that this will help to get you back on track. Please let me know if you see any problems with what I have said.
