And God's Word has already shown that the New Jerusalem will be a literal city upon the earth. There's no way to turn that into symbolism using God's Word. It's men's doctrines that try to do that in order to try and change what God's Word reveals. The fact that Ezekiel 40 through 48 reveals a literal physical layout of the holy city on earth anchors what the New Jerusalem is in Revelation when it comes down out of Heaven to this earth.
It is definitely a literal city. I don't disagree. But my point is that it is not a city of bricks and mortar, like the Old (current) Jerusalem. The church is the people not the building. The New Jerusalem is the people not the physical city - it is the Church in her transformed, glorified and immortalized state. Not a physical building made of bricks and mortar. The Bible reveals that the New Jerusalem is Christ's Bride. Christ will not "marry" a bricks and mortar building. God has never really been interested in building physical temples or buildings, only in building His people:
1 Peter 2:5 says "you also, like living stones, are being built into a spiritual house to be a holy priesthood, offering spiritual sacrifices acceptable to God through Jesus Christ.
Eph 2:22 "And in him you too are being built together to become a dwelling in which God lives by his Spirit."
Furthermore, statements like Revelation is full of imagery and symbolism as some kind of tool to try and change the literal objects or events that God's Word uses symbology and metaphor for is to treat those things like some pagan mystic mumbo-jumbo abstraction outside reality. James, aren't you aware of how pagan mysticism crept into the Church centuries ago from Gnostic influences, especially at the school in Alexandria, Egypt? One of the main things the pagan mystery schools did was to mask the physical things of the earth using images and symbols so as to hide it from those they deemed profane (but they really meant the uninitiated into their doctrines)? Those pagan priests did that for the purpose of mass control over the minds of the peoples. Only one who petitioned to join their group would be offered a probation period as a neophyte before they would divulge the real meaning of their imagery and symbols. That is not how God uses imagery and symbols in His Word though.
Tree of life is a common idea in almost all religions including paganism. However only Christianity would say that the tree of life is Christ.
All other religions say the tree of life is anything else, but Christ.
Paganism contains an element of worshiping the creation instead of the Creator. There is nothing pagan about trees representing Christ. However, an idea that trees give life, apart from Christ, seems more of a pagan idea to me.
Revelation is full of imagery and symbolism because it's a vision. For example when God showed Peter a vision of unclean animals, it was to show him that Gentiles are clean.
Revelation says there is a Lamb on the throne, but we know it is not actually a Lamb, it is symbolic for Christ.
I don't believe there will literally be women riding beasts and big red dragons (Revelation).
I don't believe Daniel's visions meant there were actual statues of clay and iron coming to destroy nations.
These are all symbolic for kingdoms, nations, kings, people.
If we fail to see the meaning of the symbols we'll miss the true meaning.
Yes I understand how God sometimes uses the tree as a metaphor in His Word. That doesn't mean we can go applying all mention of a tree in His Word to be nothing but a symbol. It's the Biblical context of the subject that determines when He is using the tree as a symbol for something else. We don't find that context with the explanations shown in Genesis 2 & 3 and Revelation about the Tree of Life. And when Ezekiel 47 and Revelation 22 speak of the Tree of Life and its fruits for meat and leaves for medicine in relation to a specific locale on earth it's easy to know that is not being given as a symbolic metaphor, especially when it is linked with God's River of Gen.2 and Ezekiel 47 which is also literal.
It's very simple. Christ said He was the life. This life is eternal life (John 17:3). We know that eating of the tree of life gives eternal life (Genesis and Revelation). Therefore the Tree of Life is Christ. 1 John 5:12 says "whoever has the Son" has life. Not "whoever has the Tree of Life", has life.
There is no other source of eternal life - other than Christ.
Jesus did not say we eat trees to get life. Jesus said we must eat His flesh and drink His blood to have life:
John 6:53 says "Jesus said to them, "Very truly I tell you, unless you eat the flesh of the Son of Man and drink his blood, you have no life in you.
This also confirms that Christ is the Tree of Life - We eat the Tree of Life to gain life, we eat Christ to gain life, therefore the Tree of Life is Christ.
All false doctrines and practices start when we put the emphasis away from Christ and onto other things such as trees, rocks, buildings, bread, wine. etc. These created things have no life in themselves. And the use of these created things as symbols, is to better explain to us the spiritual truth behind them. For example, the Catholics put emphasis on the bread and wine because they believe they are actually Christ's body and blood. So it becomes more about the bread and wine than the meaning which the bread and wine conveys.
Similarly if we believe the tree of life is some actual tree and not Christ, we may be in danger of tree worship, which is essentially pagan. Some Christians already worship trees at Christmas time.
Notice that Christ is also referred to as a rock:
1 Cor 10:4 "and drank the same spiritual drink; for they drank from the spiritual
rock that accompanied them, and that
rock was
Christ."
