Lets begin with the Greek and a literal translation:
Joh 3:16
οὕτω γὰρ ἡγάπησεν ὁ Θεὸς τὸν κόσμον,
For in this manner did God love the Kosmos [eg Creation]
ὥστε τὸν υἱὸν αὐτοῦ τὸν μονογενῆ ἔδωκεν,
So that the Son of Him the Only Begotten He gave
ἵνα πᾶς ὁ πιστεύων εἰς αὐτὸν μὴ ἀπόληται,
In order that everyone who is believing in Him should not perish
ἀλλ᾿ ἔχῃ ζωὴν αἰώνιον.
But (instead) should have Life Eternal
The first thing of note is
τὸν κόσμον,
He did not write "For God so loved human beings..."
But instead "...loved creation" - The Kosmos...
And in this is hidden the place of man in creation...
The essential place of man in God's Creation...
For without man, there is no creation as God intends creation...
When man fell, so also fell creation...
And the purpose of Christ incarnating is to restore creation...
And this is done by restoring man as Divinely created...
And then uniting man to God in Christ's Ascended Body, the Church...
The Cross, then, was for the sake of the restoration of man...
Baptism is for the sake of uniting man to God...
This uniting of man and God IS a New Creation...
Christ is the God-man in creation...
A Saint is a "Godded" man in creation...
The Body of Christ has as Her members those who have been baptized into Christ and have therein put on Christ being baptized into His Death in the Hope of His Resurrection...
Enough for now!
