I mean no disrespect, but I have absolutely no idea the point you are trying to make given the context of the conversation.
It is has nothing to do with man's understanding that men will die from. It is all about Jesus so eat and drink of Him and we will be satisfied.
It is all about Jesus and being chosen in Him from the foundation of the world not about us and who we are, but Him, not about us I being chosen before the foundation of the world which is all about us, but about being chosen in Him which is all about Christ.
John 6:45
It is written in the Prophets: ‘They will all be taught by God.’ Everyone who has heard the Father and learned from him comes to me.
John 6:63
The Spirit gives life; the flesh counts for nothing. The words I have spoken to you—they are full of the Spirit and life.
John 14:24
Anyone who does not love me will not obey my teaching. These words you hear are not my own; they belong to the Father who sent me.
John 10:30
I and the Father are one.”
Matthew 11:29
Take my yoke upon you and learn from me, for I am gentle and humble in heart, and you will find rest for your souls.
It goes goes back to the beginning that wickedness comes from us not God when we worshiped the created thing over the creator, Satan's word.
Genesis 3
1 Now the serpent was more crafty than any of the wild animals the Lord God had made. He said to the woman, “Did God really say, ‘You must not eat from any tree in the garden’?”
2 The woman said to the serpent, “We may eat fruit from the trees in the garden, 3 but God did say, ‘You must not eat fruit from the tree that is in the middle of the garden, and you must not touch it, or you will die.’”
4 “You will not certainly die,” the serpent said to the woman. 5 “For God knows that when you eat from it your eyes will be opened, and you will be like God, knowing good and evil.”
6 When the woman saw that the fruit of the tree was good for food and pleasing to the eye, and also desirable for gaining wisdom, she took some and ate it.
We are to trust in God over our own understanding and what we see, and what the devil schemes is to get us not to believe His word
Ephesians 6 :
10 Finally, be strong in the Lord and in his mighty power. 11 Put on the full armor of God, so that you can take your stand against the devil’s schemes. 12 For our struggle is not against flesh and blood, but against the rulers, against the authorities, against the powers of this dark world and against the spiritual forces of evil in the heavenly realms. 13 Therefore put on the full armor of God, so that when the day of evil comes, you may be able to stand your ground, and after you have done everything, to stand. 14 Stand firm then, with the belt of truth buckled around your waist, with the breastplate of righteousness in place, 15 and with your feet fitted with the readiness that comes from the gospel of peace. 16 In addition to all this, take up the shield of faith, with which you can extinguish all the flaming arrows of the evil one. 17 Take the helmet of salvation and the sword of the Spirit, which is the word of God.
