Contradiction with Matthew 6:19
This verse advises against laying up treasures on earth, focusing more on earthly aspects, whereas John 6:27 speaks about not laboring for perishable food but for eternal sustenance.
Matthew 6:19: Lay not up for yourselves treasures upon earth, where moth and rust doth corrupt, and where thieves break through and steal:
Contradiction with Genesis 3:19
This verse states that humans will eat bread by the sweat of their brow, emphasizing physical labor for food, in contrast to John 6:27, which advises against laboring for perishable food.
Genesis 3:19: In the sweat of thy face shalt thou eat bread, till thou return unto the ground; for out of it wast thou taken: for dust thou [art], and unto dust shalt thou return.
Contradiction with Ecclesiastes 5:18
This verse suggests that it is good and fitting to enjoy the fruits of one's labor, focusing on earthly enjoyment, which contrasts with the guidance in John 6:27 to labor for spiritual sustenance.
Ecclesiastes 5:18: Behold [that] which I have seen: [it is] good and comely [for one] to eat and to drink, and to enjoy the good of all his labour that he taketh under the sun all the days of his life, which God giveth him: for it [is] his portion. [It is good...: Heb. there is a good which is comely, etc] [all the days: Heb. the number of the days]
Paradox #1
John 6:27 might seem to contradict other biblical teachings about work and priorities. This verse emphasizes seeking spiritual rather than physical food, which could seem at odds with verses that stress the importance of hard work and providing for one's physical needs. However, these teachings can be harmonized by understanding that the focus should ultimately be on spiritual well-being, while also responsibly managing physical needs.
