The world view is that we have to "see" to believe. Hence the phrase seeing is believing; while on the other hand the kingdom principle is to believe then we see. This seems to be the practical truth, The kingdom of God is upside down and backward from the world and always will be until who is perfect returns!!!
In John 6:48-51 it reads in The Passion , "I AM the true Bread of Life. Your ancestors ate manna in the desert and died. But standing here before you is the true Bread that comes out of heaven, and when you eat this Bread you will never die. I alone am this living Bread that has come to you from heaven. Eat this Bread and you will live forever. The living Bread I give is my body, which I will offer as a sacrifice so that all may live." There is a difference between eternal life and living forever. The only reason I would die is if there is a record of sin in my DNA. I do not need to die, none of us do. But we need to undergo transformation by applying the body and blood of Jesus. The body and blood of Jesus carry the record of the DNA of God. We can age and die, or we can take the body and blood of Jesus within ourselves, and live forever!. Jesus says in John 6:58, "I am not like the bread your ancestors ate and later died. I am the living Bread that comes from heaven.
