I am wondering if we will eat in heaven, and what?  Will the fruit bearing trees contain actual food, or is this figurative for the blessings of spirit? Thank you, Judy

Judy,
    Your question is a good one. I should add the topic to my "topics" list accessible from the home page. Heaven is real. I think people often are interested in it to avoid hell, which is also misunderstood but that's another topic.

    To start I'll remind you of a verse: 1 Cor. 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." This means we don't know exactly what it will be like. I believe God has two reasons. First, we couldn't understand it and would be tempted to give up hope. Second, we would cease to enjoy the remaining bright aspects of our present life. That might be like a modern luxury car shown briefly 3000 years ago. Then telling the people they would be able to own one but would have to wait.
    But back to the Bible. The last chapters of Isaiah tell of the joy the chosen people would have had by simply living the way of righteousness. But it becomes clear as you read, that the new earth is being described, too. For your specific question about trees see is6521 and Rev. 22:2 (linked above). And about eating, mr1425, re1909. Some of the verses are more clearly literal than others.
    Aside from the physical aspects of heaven, I'm eager to be with people who love the Lord. We will have all eternity to make friends. God Himself being present (Rev. 21) Then we will have the joy of knowing the angel that was our protector and other angels who have lived in the presence of God. Then we will know Jesus better and be enraptured by the beauty of His character.
    We will act and do and think and plan unhampered by sin and its effects. What joy!
    I believe the description of the city as a cube in Rev. 21 is symbolic re2109. The dimensions being equal show that it is perfect and represent the people who are also the city (as we use the word, city, two ways here) is6212. The foundations tell us of it's secure base and the gates the perfect freedom. Could walls and gates and dimensions be also real? Sure. I don't believe we have long to find out!
