Kosta50: I think you [Dr. Eckleburg] are reading way too much into it. The word "spirit" simply means "breath" (pneuma). So long as you are breathing you are alive. The ancients believed that "life" was in the breath. Those who breathe are "quickened"; those who don't are dead. We simply say breathing and not breathing.
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. – John 3:6-8
Jesus answered and said unto him, Art thou a master of Israel, and knowest not these things? Verily, verily, I say unto thee, We speak that we do know, and testify that we have seen; and ye receive not our witness.
If I have told you earthly things, and ye believe not, how shall ye believe, if I tell you [of] heavenly things? – John 3:9-12
To God be the glory!
Not, not God, A-G, St. John (we think). Not even the Church says it's God, but According to John, not according to God.
To the contrary, the breath is not physical but spiritual
In your dreams. You must then believe that bats are birds, because "God" says so. What we breathe in and out of our lungs is not spirit, but gas. It has to do with oxygen exchange so that our cells may live.
You quote Genesis 2:7 and all it says that God gave Adam the first breath. The organism takes over form there because it was built to breathe. That's what happens with newborn babies.
Do you believe the earth is sitting on four pillars and earthquakes happen when God shakes them? You should. "God" says so.
If there is an entity called a spirit, an immaterial existence, then it will not be in a form of anything physical, including breath, but separate from it because its nature (essence) will be different.
And just as we know that dogs are not humans and humans are not dogs and can never mix because their natures are different, for only canines can have canine offspring and only humans can have human offspring, and only divine can beget divine, we then know that if there is a spirit that gives life to our body it is nothing physical, measurable, visible, spacial, or in any way quantifiable.
We believe there is, but we have no proof of it.
If I have told you earthly things, and ye believe not, how shall ye believe, if I tell you [of] heavenly things? – John 3:9-12
I agree. How do you know that what you believe are "heavenly" things when you have difficulty believing earthy ones?
God [is] a Spirit: and they that worship him must worship [him] in spirit and in truth. – John 4:24
How do you worship a Spirit in spirit? I would imagine it should be with spirit. Obviously St. John doesn't think we have can. Rather he uses it as "Love is worshiped in love,"Hope is worshiped or "in hope," or "Truth is worshiped in truth."
It's an unorthodox way of using adjectives, such as "lovingly," "hopefully," "truthfully," etc. So then we can say that we believe God is a Spirit and we worship Him spiritually, not carnally as the pagans do.
