The Greek verb diaporeo means to be thoroughly perplexed, at a complete loss, or greatly puzzled. The dia intensifies the perplexity — this is not mild confusion but deep bewilderment about how to proceed.
Herod Antipas was diaporeo about Jesus (Luke 9:7) — his guilty conscience and the reports of miracles left him unable to make sense of who Jesus was. The disciples similarly were diaporeo about what the resurrection meant (Acts 10:17). Divine reality regularly produces this kind of perplexity in those who encounter it. It is not a failure of faith but often a necessary first step toward genuine understanding.
