"Claims that some form of consciousness persists after our bodies die and decay into their constituent atoms face one huge, insuperable obstacle: the laws of physics underlying everyday life are completely understood, and there’s no way within those laws to allow for the information stored in our brains to persist after we die. If you claim that some form of soul persists beyond death, what particles is that soul made of? What forces are holding it together? How does it interact with ordinary matter?" Sean Carrol (Phd Physics Harvard)
The soul is not physical and consists of the mind, emotions, will and basic personality. The mind uses the brain in this physical realm and then when we die, it moves on without the body. This is beyond physics, it's extra-dimensional. We can see neuro-transmitters, the chemicals used to send messages and other brain activities, but the mind, tough integrated, is separate. God is not physical, He is spirit and has a mind, emotions, will, creativity, etc. When the Bible says we are made in his image, this invisible self is the image it's talking about.
Just what is the tree of life or even the bread of life
Jesus said, "
I am the vine, you are the branches". Symbolically, He is the tree of life. He said, "I am the way, the truth and
the life ..." "...you must eat my flesh and drink my blood" is also symbolic for consumming the word of God. He is the Word, He is the bread of life. Read the New Testament and you are eating and nourishing yourself. Believe in Him, ask for forgiveness and you are being washed by His blood sacrifice. Taking communion and drinking the wine/grape juice symbolizes his blood sacrifice that we do regularly to remember what He did.
He ate fish and honey, after the resurrection
.
Angels are spirits that can appear in the form of a human and eat. The Bible says that it is possible that we have entertained angels at times. Jesus' resurrected body
is extra-dimensional, able to appear and disappear, become physical, eat and fly or beam himself up to heaven or so to speak. Our eternal bodies will be like that! For all you atheists, don't bother challenging this now, this is too incredible for you to understand.
