Alright well...as for the part about manna, and how the Lord provided it for the Israelites in the wilderness during their Exodus from Egypt, when Moses led them out. That was on earth, in Egypt, not in heaven. Think about it, we will have a ''new body'' in heaven, it'll be a spiritual one just like Jesus. So again my point of we won't be hungry. That if anything, we'll only be hungry spiritually. To serve the Lord in heaven, to sing and shout praises to Him and everything. I'm not even sure that we'll be spiritually hungry, because our spirit/soul will be in heaven with the Lord. Also that Jesus took the bread and whine, blessed it, and said that whosoever drank of the whine which represented His blood which was shed for us, and who ate of the bread, which was a symbol of His flesh that was beaten for us, and how He died and rose again for us, that they would never hunger or thirst again.(I still stick with this).
They were on earth and in a fleshly body, thereofore, they did hunger physically/fleshly. The thing is we won't have a fleshly/physical body like we do here on earth, we'll have a spiritual one. Also Jesus said that He is the bread of life. Take a look at this.
John 6:34-37 Then said they unto him, Lord, evermore give us this bread. And Jesus said unto them, I am the bread of life: he that cometh to me shall never hunger; and he that believeth on me shall never thirst. But I said unto you, That ye also have seen me, and believe not. All that the Father giveth me shall come to me; and him that cometh to me I will in no wise cast out.
1 Corinthians 15:38-46 But God giveth it a body as it hath pleased him, and to every seed his own body. All flesh is not the same flesh: but there is one kind of flesh of men, another flesh of beasts, another of fishes, and another of birds. There are also celestial bodies, and bodies terrestrial: but the glory of the celestial is one, and the glory of the terrestrial is another.There is one glory of the sun, and another glory of the moon, and another glory of the stars: for one star differeth from another star in glory.So also is the resurrection of the dead. It is sown in corruption; it is raised in incorruption: It is sown in dishonour; it is raised in glory: it is sown in weakness; it is raised in power:It is sown a natural body; it is raised a spiritual body. There is a natural body, and there is a spiritual body.And so it is written, The first man Adam was made a living soul; the last Adam was made a quickening spirit. Howbeit that was not first which is spiritual, but that which is natural; and afterward that which is spiritual.
This is straight from the word of God, which is the truth. There's no debating it. So if anyone wants to call the word of God a lie, you might wanna think about it, cause it's not at all. It's the truth. Not saying that anyone's saying that or whatever, just saying my facts/proof come from there. The word of God can't be wrong. Bottom line.
