Well jesus said in John 6 we have that assurance. He said we will never die we will live forever. We will never hunger or thirst

Notice the one of many constants in that teaching.
God has everything to do with calling whom he will to his truth,first. And then those whom he calls are made able to understand the word of The word.
Immanuel=Jesus=God, is the bread of life. The blood,drink,of eternal life. Why?Because all things,including us,are of and from God. Salvation is being saved from the illusion of this subjective reality that is sinful, i.e. made separated from that understanding. Salvation is moving past that veil of illusion and ,like the scales that fell from Paul's eyes, seeing the truth of God
in Christ.
Eating the things of this world,bread that can spoil,drinking wine that can sour, are proofs eternity is not present in this material subjective realm. All is vanity.
I.E. all by our natural conscious perception,is here to be used by us,to serve our desires,and sustain our living day to day.
We witness foods spoiling, wine turning sour,wells going dry. And the flesh falling ill or ceasing to be. Impermenance.
For a worldly,flesh,consciousness,that is life in the flesh. Which is a condition that is perpetuated throughout the human species as we are born and are raised to that understanding.
Which is why only God can pierce that veil and move our mortal worldly consciousness unto spiritual union of understanding. Because all is of and from God.
