Will there be animals, birds, and vegetation in the eternal state?
There will certainly be vegetation in the eternal state, for the Tree of Life has leaves. The animal kingdom and birds are also expected, along with other things that enhance creation. These will serve God's purpose and enhance our eternalness.
Les explains that the Tree of Life will have leaves, so there will be vegetation in the eternal state, much like we have today. He also says he thinks there will be an animal kingdom, birds, and other things that enhance creation. The Tree of Life yields fruit every month, indicating a time factor in eternity, and its leaves are therapeutic, not for healing since there is no sickness. The fruit is for our pleasure and enhances our eternalness.
