Contradiction with Jeremiah 17:10
Contradicts John 6:64 which implies Jesus' knowledge of all, as it asserts that it is the Lord who searches the heart and tries the reins, suggesting exclusion of others including Jesus.
Jeremiah 17:10: I the LORD search the heart, [I] try the reins, even to give every man according to his ways, [and] according to the fruit of his doings.
Contradiction with 1 Samuel 16:7
Contradicts John 6:64 by emphasizing that only the Lord looks on the heart and not humans, challenging the claim of Jesus' omniscience implied in John 6:64.
1 Samuel 16:7: But the LORD said unto Samuel, Look not on his countenance, or on the height of his stature; because I have refused him: for [the LORD seeth] not as man seeth; for man looketh on the outward appearance, but the LORD looketh on the heart. [outward...: Heb. eyes]
Contradiction with Mark 13:32
Contradicts John 6:64 as it states that Jesus does not know the day or the hour, thus questioning His complete foreknowledge mentioned in John 6:64.
Mark 13:32: But of that day and [that] hour knoweth no man, no, not the angels which are in heaven, neither the Son, but the Father.
Contradiction with Philippians 2:7
Contradicts John 6:64 by emphasizing Jesus' human limitations, challenging the idea of Him knowing from the beginning who would not believe.
Philippians 2:7: But made himself of no reputation, and took upon him the form of a servant, and was made in the likeness of men:
Contradiction with John 12:47
This verse contradicts John 6:64 as it portrays Jesus not judging, whereas John 6:64 implies knowledge and thereby a form of judgment about belief.
John 12:47: And if any man hear my words, and believe not, I judge him not: for I came not to judge the world, but to save the world.
Paradox #1
John 6:64 could be seen as having a contradiction because it suggests that Jesus knew some of his followers did not truly believe in him, yet he allowed them to follow him. Some might see a conflict here, as it raises questions about why he would keep followers who lacked genuine belief, possibly leading to questions about free will and divine foreknowledge.
