One of things that attracted to me to Christianity was that compared to all the other religions of the world it presented a two-creation model as opposed to a one-creation model. In Christianity, the ultimately perfect creation follows after God uses the present “very good” creation to permanently eradicate evil and suffering. As I explained in my book, Why the Universe Is the Way It Is, God designed the laws of physics that govern our universe as tools to restrain to some degree the expression of human sin and evil. The Bible declares that these laws of physics have remained unchanged since the cosmic creation event (Jeremiah 33 and Romans 8) and will remain in effect until the full number of humans God intends to redeem have in fact been redeemed (Romans 8 and Revelation 20). Once that full number has been reached God will deliver redeemed humanity from this universe, remove the universe from existence, and place all of redeemed humanity into the new creation where those redeemed humans will enjoy life with radically different laws of physics and radically different dimensions.
This biblical theology implies that gravity, electromagnetism, and thermodynamics always have been present in the universe. Consequently, as Solomon states in Ecclesiastes and Paul states in Romans everything in the universe is subject to a pervasive law of decay. This decay implies God’s creatures in the universe, minus access to the tree of life, must experience physical death. However, God designed the universe, Earth, and Earth’s life so as to minimize the suffering of his creatures from death. God’s creation of carnivores, for example, actually lessens the degree of disease, suffering, and death on the part of the herbivores that the carnivores prey upon.
In my book, Hidden Treasures in the Book of Job, I describe the roles of the nephesh (soulish) animals in teaching us humans vitally important spiritual lessons. As our sin ruins the depth of relationship we can enjoy with a nephesh animal, so also it ruins the depth of relationship we can have with God. As it takes a higher being to tame a nephesh animal, so also it takes a higher Being to tame a human. As the full potential of a nephesh animals only is manifested when it is strongly bonded to a human being, likewise the full potential of a human is only manifested when that human is strongly bonded to God. God designed the nephesh animals to serve and please and to form powerful emotional bonds with us. When one of our pets dies, we feel a deep sense of loss and grief. Likewise, God feels a deep sense of loss and grief when we who were designed to serve, please, and relate to him run away from him or pretend he does not exist. For a complete list of the spiritual lessons that the nephesh animals teach us see Hidden Treasures in the Book of Job.
In Why the Universe Is the Way It Is, chapter 13, I describe the physics of the new creation. Yes, it is a realm where for the rest of eternity there will be no death, decay, sin, evil, pain, grief or suffering. it is realm where are relationships will be geometric and not linear. Love will be magnified beyond what any of us can think or imagine.
