And I saw a new heaven and a new earth:
for the first heaven and the first earth were passed away;
and there was no more sea.
(Revelation 21:1)
while they still did not believe it because of joy and amazement, He asked them,
“Do you have anything here to eat?”
they gave Him a piece of broiled fish, and He took it and ate it in their presence.
(Luke 24:41-43)
He said to them,
“I have eagerly desired to eat this Passover with you before I suffer. For I tell you,
I will not eat it again until it finds fulfillment in the kingdom of God."
(Luke 22:15-16)
the angel said to me, “Write this: Blessed are those who are invited to the marriage supper of the Lamb.”
And he said to me, “These are the true words of God.”
(Revelation 19:9)
that day when I drink it new with you in my Father's kingdom.
(Matthew 26:29)
But we know for a fact that resurrection is of the spirit and even Jesus resurrected spiritually immediately after dying:
Matt 27:
50And when Jesus had cried out again in a loud voice, he gave up his spirit.
51At that moment the curtain of the temple was torn in two from top to bottom. The earth shook, the rocks split 52and the tombs broke open. The bodies of many holy people who had died were raised to life. 53They came out of the tombs after Jesus’ resurrection and e went into the holy city and appeared to many people.
So, the fleshly display including eating was only meant for people to believe but the spiritual is where everything happens.
