Luke 24 describes a scene before Jesus rose into heaven in a spiritual body. See my post to Jane_Doe on my reason to believe Jesus ascended into heaven with a spiritual body and not a glorified fleshly body.
I concede that the verses you shared give the impression that Jesus, like a specter, was vanishing and walking through closed doors however, taking those verses with the others in the Bible on the topic of the spiritual body I read those differently. It is not clear cut that Jesus walked through the closed door but only that he was in the room with the door closed. The same language used in Luke 24:31 about Jesus vanishing is reflected elsewhere when it talks about Jesus walking away unnoticed such as:
(Joh 8:59) Then took they up stones to cast at him: but Jesus hid himself, and went out of the temple, going through the midst of them, and so passed by.
I’m not saying you don’t have a valid point but for me that view doesn’t fit with scriptures on the topic of spirit vs flesh.
So am I mistaken in thinking, from your questions, that the Seventh Day Adventist also believe we will have fleshly bodies in heaven?
Yes--as Adam and Eve had. People, seem to want to think that spiritual means we will be some sort of "spiritual plasma" floating around instead of the condition of the heart---I don't see anything to suggest that, otherwise, why even bother with a resurrection of the dead? Some believe that is why we can not see the realm in which God, and even the fallen angels live. But, we can when our eyes are opened by God.
(2Ki 6:17) And Elisha prayed, and said, LORD, I pray thee, open his eyes, that he may see. And the LORD opened the eyes of the young man; and he saw: and, behold, the mountain
was full of horses and chariots of fire round about Elisha.
He can also close those eyes---as Jesus did in the verse you quoted:
(Joh 8:59) Then took they up stones to cast at him: but Jesus hid himself, and went out of the temple, going through the midst of them, and so passed by.
I can't hide myself from the eyes of those around me, if they throw stones at me, they'll hit me.
I see no reason to impose limitations on what God will allow the human body to do, or see. God made these physical laws, Her does not need to abide by them.
(Dan 3:22) Therefore because the king's commandment was urgent, and the furnace exceeding hot, the flame of the fire slew those men that took up Shadrach, Meshach, and Abednego.
(Dan 3:23) And these three men, Shadrach, Meshach, and Abednego, fell down bound into the midst of the burning fiery furnace.
(Dan 3:24) Then Nebuchadnezzar the king was astonied, and rose up in haste,
and spake, and said unto his counsellors, Did not we cast three men bound into the midst of the fire? They answered and said unto the king, True, O king.
(Dan 3:25) He answered and said, Lo, I see four men loose, walking in the midst of the fire, and they have no hurt; and the form of the fourth is like the Son of God
(Act 28:5) And he shook off the beast into the fire, and felt no harm.
(Act 28:6) Howbeit they looked when he should have swollen, or fallen down dead suddenly: but after they had looked a great while, and saw no harm come to him, they changed their minds, and said that he was a god.
If we are spirit only, then why do we have access to the tree of life and the water if life--food and water--basic human needs. We get to have trees, animals, live in the house of God, we will have eyes that see and ears that hear
(Rev 21:4) And God shall wipe away all tears from their eyes; and there shall be no more death, neither sorrow, nor crying, neither shall there be any more pain: for the former things are passed away.
(1Co 2:9) But as it is written, Eye hath not seen, nor ear heard, neither have entered into the heart of man, the things which God hath prepared for them that love him.
We will be changed, that is clear--from mortal corruptible bodies, to incorruptible, immortal ones. Jesus made a vow before He died---
(Mat 26:29) But I say unto you, I will not drink henceforth of this fruit of the vine, until that day when I drink it new with you in my Father's kingdom.
We'll drink more than water. We'll have voices, we will sing and praise the Lord. I don't see any of this as being some sort of formless vapor.
When Jesus spoke to Mary after His resurrection he said:
(Joh 20:17) Jesus saith unto her, Touch me not; for I am not yet ascended to my Father: but go to my brethren, and say unto them, I ascend unto my Father, and your Father; and
to my God, and your God.
However, a little later, He said this to hos diciples
(Luk 24:39) Behold my hands and my feet, that it is I myself:
handle me, and see; for a spirit hath not flesh and bones, as ye see me have.
He had not yet ascended to His Father when He met Mary, and she could not touch Him--- yet a little later He tells His disciples to touch Him. So, He must have ascended to His Father in between.
HHMMM------this is off topic. Sorry. Let's not derail. This is about Mormon believes!----ooops!
