Jesus shed His blood on the cross.
The body He has now is NOT the body He was born into.
It is resurrected and transformed.
If it wasn’t, He could not have appeared through closed doors, nor survived the ascension.
Just because the body LOOKS the same, does not mean that it is intrinsically the same, that it is made of the same material as our human bodies, which can only survive within a very narrow range of parameters.
Perhaps applicable:
1 Corinthians 15 King James Version (KJV)
20 But now is Christ risen from the dead, and become the firstfruits of them that slept.
21 For since by man came death, by man came also the resurrection of the dead.
22 For as in Adam all die, even so in Christ shall all be made alive.
23 But every man in his own order: Christ the firstfruits; afterward they that are Christ’s at his coming.
And this same chapter:
50 Now this I say, brethren, that flesh and blood cannot inherit the kingdom of God; neither doth corruption inherit incorruption.
51 Behold, I shew you a mystery; We shall not all sleep, but we shall all be changed,
52 In a moment, in the twinkling of an eye, at the last trump: for the trumpet shall sound, and the dead shall be raised incorruptible, and we shall be changed.
53 For this corruptible must put on incorruption, and this mortal must put on immortality.
54 So when this corruptible shall have put on incorruption, and this mortal shall have put on immortality, then shall be brought to pass the saying that is written, Death is swallowed up in victory.
55 O death, where is thy sting? O grave, where is thy victory?
