Contradiction with Proverbs 16:9
This verse explains that a man's heart devises his way, but the Lord directs his steps, suggesting human plans are ultimately subject to God's will, which contradicts the implication of predetermined martyrdom in John 21:19.
Proverbs 16:9: A man's heart deviseth his way: but the LORD directeth his steps.
Contradiction with Ecclesiastes 8:7
This verse indicates that no one knows what is to come, which contradicts the clear prediction of Peter's death by Jesus in John 21:19.
Ecclesiastes 8:7: For he knoweth not that which shall be: for who can tell him when it shall be? [when...: or, how it shall be?]
Contradiction with Hebrews 11:1
This verse describes faith as assurance in things not seen, implying uncertainty, whereas John 21:19 clearly predicts Peter's manner of death, implying certainty.
Hebrews 11:1: Now faith is the substance of things hoped for, the evidence of things not seen. [substance: or, ground, or, confidence]
Contradiction with James 4:14
This verse emphasizes the uncertainty of life, contrasting with the specific prediction of Peter's death in John 21:19.

Contradiction with Matthew 16:25
This verse suggests that those who lose their life for Christ's sake will find it, which contrasts with the clear foreshadowing of literal death in John 21:19.
Matthew 16:25: For whosoever will save his life shall lose it: and whosoever will lose his life for my sake shall find it.
