Brainwashing? Christianity seems to be taking weird steps, here at least.

[Sigurd]

This is a refreshing discussion here at the .org.
I want to dissect too.

...
We are born as slaves to sin in this world. However, numerous characters in the OT speak of God knowing them before they were born, and David says he was specifically chosen by God ...
...
Flesh comes from flesh, that is true - our bodies are merely the result of biological processes. And that's why we shouldn't be too concerned about them. Our spirit is much more important, it is created by God Himself ...

The notion that God knew someone before they were born suggest life before birth. And predestination cold translate to preordination, an intriguing thought, and I believe, doctrine in certain branches of Christianity.

No, God is with out time. Sometimes He just intervenes in earth and plays along to the dimension of time so we can understand what He is doing, whether it is speaking to Moses or whatever.

I believe there can only be one dimension, one time line, and everything that happens in it is inevitable. Otherwise the prophecies in the Bible could never have been predicted.

Having different definitions of who or what God is could lead to thrilling discussion on time and space. Considering the story behind how the immaterial God came to be, this very idea should be questioned my modern Christians.

God never randomly punishes sinners, He only ever punishes his children.

Tell that to the pre-deluge people and the inhabitants of Sodom and Gomorrah.

Now, if you chose God before coming into this earth, then God will not deny you His gift, and will overcome all the wickedness in us, overcome us even if we resist Him, and give us the gift that we willingly accepted before Satan corrupted us.

Now this is a Mormon doctrine called: pre-mortal life and the choice made at the council in heaven.

Of course they could. God could predict different things in different time lines. In any case the prophecies are often obscure and the only definitely fulfilled ones are the ones concerning Jesus and it is acceptable to say that in an otherwise changeable universe God, and therefore Christ are constant.

To predict things would be simple for an eternal being having omnipotence. Whatever you predict, you will make sure it happens. No need for fate or predestination.

All people are God's children, all people are descended (according to the Bible) From Adam, that is why we sin to begin with.
...
Something to think about: Man chose Sin when he did not know what Sin was.

One of the things I based my leave of the Lutheran church was the notion of original sin and babies going to hell if they were not baptized.

Frankly, this is doctrine again, and very late doctrine at that.

First principles:

God is Just.

How can a Just God create some to be damned and others not, have us make the choice before we are born, which is determined by our nater He has made, and then force us to suffer through this life?

Yes... I think this is the basis for the Christian need of a redeemer. As I understand it God is perfectly just and executes perfect justice.
Like any law that demands payment for breaking it, so does the law of God. No mercy involved.
If you break the law, i.e sin, you are damned from heaven.
Christ atoned for every sin past present and future. He is the mediator with God (Justice).
Justice demands payment and Christ payed up for all (believers and nonbelievers).

This is where it gets tricky. Christ demands something for his leverage with justice. Faith, repentance and baptism is what he asks in addition to some other minor stuff.
Apparently in some denominations all it takes is to speak his name and you will magically be transformed to a clean being, never to do evil again and justice will not have claim on you.
This is what according to Christianity mankind can chose freely. To follow Christ. To chose freedom and heaven or the full weight of justice on their own shoulders and paying out of their own pocket in Gehenna.
