Romans 1:20 tells us that the invisible things of God can be understood by the things that are seen.
In John 3 Jesus tells Nicodemus that he must be born again.
Does physical birth teach anything concerning spiritual birth? If so, what?
Yes.Adam is made in the image of the water and Eve in the image of the blood.The two are to become one like the Covenants.
The spirit, water, and the blood are everywhere in his creation because the water and the blood are the two who bare witness on the earth.They are his Two Witnesses of Revelation.
Adams life giving parts have the water, and the blood and so does Eve.His testicles are in the image of the water, and the blood, and Eves Ovaries are in the image of the water and the blood.
Adams parts hang below and Eves parts hang above.
Jesus said to the scribes and Pharisees "
you are from below and I am from aboveYou are of this world.I am not of this world".
All who are unrepented are from below.
The Pharisees and Sadducees were testing/accusing John while he was baptizing people,and they were rebuked with the truth .That's why satan is the accuser.
Same thing with Adam and Eve at the garden.What did the Adam do?He blamed Eve for breaking Gods covenant rather than repenting.
When the sperm leaves Adam it is already a spirit, and the water, and the blood are there to make a way for the sperm to enter Eve.And when it enters and leave Eve,the water and the blood are there also as witnesses.Not only that,while the baby is passing over,it is being washed with the water and the blood as it leaves Eves body.That baby is born of the flesh.It was spirit before that.
The baby is blameless in Gods eyes till the baby understands right from wrong and breaks Gods covenants.
Here's another good one.God curses the serpent and says on your belly you shall crawl and dust you will eat all the days of your life.
Now Google our back bone anatomy.it looks like a serpent.Our tail bone is the serpent head.
Romans 6:11
Likewise reckon ye also yourselves to be dead indeed unto sin, but alive unto God through Jesus Christ our Lord.
John 3:14
And as Moses lifted up the serpent in the wilderness, even so must the Son of man be lifted up.
If you are lifted up and not on your belly any more, God makes a way for you by excreting the waste of the serpent out of our bodies and even that waste fertilizes the earth.
The false prophets are the tail right?so the tail is the human head.
This is why even though we are to be born of the spirit,we still struggle against the flesh.we're still of the flesh till we die.We don't have to live that way.We find rest under the vine.
It's a every day battle.God cursed the ground,the dirt.We are what we eat till the curse is gone and we can eat the fruits of heaven.
