Jesus body was sinless. Not destroyed.
When He ascended His body was then transformed into his home's substance = Heaven.
While on earth He took upon himself a "tent" of human flesh.
The Word became flesh and made his dwelling (tabernacled) among us.
We have seen his glory, the glory of the one and only Son, who came from
the Father, full of grace and truth." John 1:14
Note: Dwelling/'tabernacled' {skenoo} among us. = a temporary shelter.
"The first man was of the dust of the earth; the second man is of heaven." 1 Cor 15:47
His body is no longer of the dust of the earth.
This earth will be destroyed by fire.
