The G-d Who Does Not Change

What does it mean to change?  Is this not a temporal (time-based) concept?  Yet G-d does not change:

"For I the LORD do not change; therefore you, O children of Jacob, are not consumed," Malachi 3:6

Therefore G-d, being supra-temporal, must necessarily "pre-date" the space-time continuum:

"23 He weakened my strength in the way; he shortened my days. 24 I said, O my God, take me not away in the midst of my days: thy years are throughout all generations. 25 Of old hast thou laid the foundation of the earth: and the heavens are the work of thy hands. 26 They shall perish, but thou shalt endure: yea, all of them shall wax old like a garment; as a vesture shalt thou change them, and they shall be changed: 27 But thou art the same, and thy years shall have no end," Psalm 102:23-27

Interesting that the Logos, which John says is Yeshua, (pre)existed as G-d at the beginning:

"In the beginning was the Word, and the Word was with God, and the Word was God," John 1:1

And that Yeshua made everything (including space-time):

"Through him all things were made; without him nothing was made that has been made," John 1:3

Even Yeshua Himself understood this when He prayed:

"And now, Father, glorify me in your presence with the glory I had with you before the world began," John 17:5

But the only way to pre-exist at the beginning (of time) is to be omni-present.  For time is but a measurement of movement through space (i.e. the modern concept of time is that it is corollary with space and therefore accurately termed "space-time") and, thus, to be unlimited to time is to be unlimited to space (omni-present).  

Now we know that omnipresence is an incommunicable attribute of G-d Himself.  And since we know that G-d is a Unity then it follows that omnipresence can only exist alongside the other attributes of G-d.  And so a Being that is omnipresent is also omniscient and omnipotent.
