What would men of the year 20 have thought amniotic fluid was ?
Water.
Eisegesis. No one handed someone a cup of amniotic fluid to someone when they said they were thirsty and asked for some water to drink.
What do women, even today, say when their water breaks ?
"My water broke!"
It isn't literally just water regardless of if people say that.
Nic' didn't understand that the water birth pertained to a mother and child relationship, while the Spirit birth pertained to a relationship with God.
First birth from mom, second birth from God.
Nic didn't understand what Jesus was talking about because Jesus wasn't referring to live birth. Otherwise, Nic would have understood exactly what Jesus was saying and there would have been no need to lecture him.
You think Nicodemus didn't believe in live birth? That isn't the point Jesus was making.
John 3
12If I have told you about earthly things and you do not believe, how will you believe if I tell you about heavenly things?
Don't you see that the "water" birth was of the earth while the "Spirit" birth was from heaven ?
That would mean there are three births.
Mom's, John's, and the Spirit's.
People getting baptized by John were not getting re-born.
Heaven, but only for the remission of sins.
Being born from a woman is the first birth, and Jesus says men need to be born again.
I disagree, as I have never read of anyone being reborn at John's baptism.
Yes, to fulfill all righteousness.
Not for the remission for past sins or to be reborn.
Okay we disagree. There are multiple schools of thought on this, but being born from a woman isn't something that people went around teaching in the Bible. They referred to water baptism with high frequency.
They won't need to struggle against their flesh anymore, as Paul says it was destroyed...in Rom 6:6..."Knowing this, that our old man is crucified with him, that the body of sin might be destroyed, that henceforth we should not serve sin."
And again in Gal 5:24..."And they that are Christ's have crucified the flesh with the affections and lusts."
I wouldn't recommend quoting single lines from Romans that proof text what you're trying to say. There is a lot going on in this book and just as much that, when isolated from all context, contradicts your point.
Did you read about Paul's struggle with sin in Romans 7?
14We know that the law is spiritual; but I am unspiritual, sold as a slave to sin.
15I do not understand what I do. For what I want to do, I do not do. But what I hate, I do.
16And if I do what I do not want to do, I admit that the law is good.
17In that case, it is no longer I who do it, but it is sin living in me that does it.
18I know that nothing good lives in me, that is, in my flesh; for I have the desire to do what is good, but I cannot carry it out.
19For I do not do the good I want to do. Instead, I keep on doing the evil I do not want to do.
20And if I do what I do not want, it is no longer I who do it, but it is sin living in me that does it.
21So this is the principle I have discovered: When I want to do good, evil is right there with me.
22For in my inner being I delight in God’s law.
23But I see another law at work in my body, warring against the law of my mind and holding me captive to the law of sin that dwells within me.
24What a wretched man I am! Who will rescue me from this body of death?
25Thanks be to God, through Jesus Christ our Lord! So then, with my mind I serve the law of God, but with my flesh I serve the law of sin.
Temptation won't end because of repentance, baptism, or rebirth: but service to sin will ! (John 8:32-34)
People still sin. Hence there are warnings to not continue in sin. Do you know what sin is?
