...does it have to do with His second coming/appearing as well?
Yes. For Jesus Christ wasn't resurrected as a disembodied spirit, but was resurrected in his fully-human
flesh and bones body (Luke 24:39, Hebrews 2:17). That's why his tomb was empty (Matthew 28:6) and why he still had the wounds of the crucifixion on his resurrection body (John 20:25-29). And Luke 24:39 didn't stop being true once Jesus ascended into heaven, for Jesus remains our fully-human mediator (1 Timothy 2:5); he will remain our fully-human high priest forever (Hebrews 7:24-26), in human flesh, just like us (Hebrews 2:17). And when he returns he will still have the wounds of the crucifixion on his body (Zechariah 13:6, Zechariah 12:10-14).
Beware the Gnostic lie that Christ isn't in the flesh, for it will be one of the key deceptions of the coming Antichrist (1 John 4:3, 2 John 1:7). The Gnostics mistakenly think that flesh is evil in itself, and that only that which is pure spirit can be good. But Jesus proves that flesh isn't evil in itself, for he has been made flesh (John 1:1,14, Romans 1:3, Luke 24:39) and remains wholly without sin (Hebrews 4:15). Genesis also proves that flesh isn't evil in itself, but was created by God himself as something very good (Genesis 1:31).
We know that Adam and Eve were flesh because they were the progenitors of the human race alive today, and we know that Adam and Eve were immortal before they fell into sin because it was only their falling into sin which made them become mortal (Genesis 2:17). So Adam and Eve started out as immortal flesh. So the future resurrection and changing of the saved into immortal flesh bodies like Jesus has (1 Corinthians 15:21-23,51-53, Philippians 3:21, Luke 24:39, Romans 8:23-25) will simply be God allowing all of saved humanity to partake of the original, very good, immortal flesh condition of Adam and Eve in the Garden of Eden before their fall into sin.
Also beware the more-general Gnostic lie that the created, physical universe is evil in itself and that only a purely-spiritual heaven can be good, for this lie is employed by Gnosticism to revile the Creator YHWH as some sort of evil, tyrant god, who Gnosticism says created the physical universe only as a foul prison house for the free spirits of humans, who Gnosticism says by some accident fell from a purely-spiritual heaven into the physical universe and became trapped within physical bodies. No doubt the coming Antichrist will employ this lie as part of his utter reviling of YHWH (Revelation 13:6, Daniel 11:36). But Genesis shows that the physical world was originally created by YHWH as something very good (Genesis 1:31).
And the Bible shows that the whole plan of Creation wasn't that humans, who are both flesh and spirit (1 Thessalonians 5:23, Luke 24:39), would become purely-spiritual ghosts and float forever on clouds in a purely-spiritual heaven with God, but that God would become both flesh and spirit like man (John 1:1,14) and that God would ultimately come down out of heaven to live with man forever on a new earth (Revelation 21:1-4), just as God had walked on the earth in the Garden of Eden with Adam and Eve (Genesis 3:8).
And on the new earth all of saved humanity will be allowed to eat from the tree of life (Revelation 2:7, Revelation 22:2,14), just as Adam and Eve hadn't been forbidden to eat from it in their unfallen state (Genesis 2:9,16-17). So, with regard to saved humans, God will completely undo the effect of the fall of Adam and Eve. All of saved humanity will be able to live in an earthly paradise forever with God (Revelation 2:7), just as Adam and Eve and all their descendants might have done had not Adam and Eve fallen into sin.
So beware the Gnostic lie. Beware the Antichrist.
