Hi there Mantis.
Where did you get the idea that we will live on a partially restored earth with our new bodies.?
Apostle Peter looked for a fully restored earth at the coming of the Lord , where only righteousness will dwell.
2Pet 3
10
But the day of the Lord will come like a thief, in which the heavens will pass away with a roar and the elements will be destroyed with intense heat, and the earth and its works will be burned up.
11 Since all these things are to be destroyed in this way, what sort of people ought you to be in holy conduct and godliness,
12 looking for and hastening the coming of the day of God, because of which the heavens will be destroyed by burning, and the elements will melt with intense heat!
13 But according to His promise we are looking for new heavens and a new earth, in which righteousness dwells.
14 Therefore, beloved, since you look for these things, be diligent to be found by Him in peace, spotless and blameless,
15 and regard the patience of our Lord as salvation; just as also our beloved brother Paul, according to the wisdom given him, wrote to you,
[ Quote Mantis ] With our new spiritual or metaphysical bodies will we feel pain? I know in the new earth there will be no pain or death but on the partially restored earth it seems like we would still need to feel pain. What say you?]
When Jesus comes again we will be like him for we shall see him as he is. We will have a body like his Glorious body.
Does Jesus feel any pain? = no. Neither shall we.
PHIL 3
20 But [we are different, because] our citizenship is in heaven. And from there we eagerly await [the coming of] the Savior, the Lord Jesus Christ; 21 who, by exerting that power which enables Him even to subject everything to Himself,
will [not only] transform [but completely refashion] our earthly bodies so that they will be like His glorious resurrected body.
1 John 3:2
Beloved, we are [even here and] now children of God, and it is not yet made clear what we will be [after His coming]. We know that when He comes
and is revealed, we will [as His children] be like Him, because we will see Him just as He is [in all His glory].
