John 18:32
“that the word of Jesus might be fulfilled, which he spoke, signifying by what kind of death he should die.”
What does John 18:32 mean?
Jesus had predicted earlier that he would be "lifted up" (crucifixion was execution by lifting a person up on a cross), and John points out that events unfolded in a way that fulfilled exactly what Jesus said. Roman crucifixion was the method that made this specific death possible, whereas Jewish law at that time would have called for stoning. Even the details of how Jesus died weren't random or tragic accidents, but aligned with what he'd already spoken about himself. For those reading John's gospel, this detail reinforces that Jesus wasn't caught off guard by his execution, and that God's purposes were being worked out even in the darkest moment.
