Why did God require a sacrifice of Himself to Himself?

[Caecilian]

yoou're positing that the eternally linving element and the human element are posited for the same purpose. His sacrifice wasn't his death, his sacrifice was his coming and his suffering.

Thats still nonsense.

How can his 'coming' be a sacrifice if hes supposed omnipresent anyway:

7 Where can I go from Your Spirit?
Or where can I flee from Your presence?
8 If I ascend to heaven, You are there;
If I make my bed in Sheol, behold, bYou are there.
9 If I take the wings of the dawn,
If I dwell in the remotest part of the sea,
10 Even there Your hand will alead me,
And Your right hand will lay hold of me.
11 If I say, “Surely the darkness will overwhelm me,
And the light around me will be night,”
12 Even the adarkness is not dark to You,
And the night is as bright as the day.
Darkness and light are alike to You.

Ps. 139:7-12

And how can an infinite being of with an eternally perfect nature be said to suffer? Doesn't suffering contradict the 'god' construct?
