New Defender's Study Bible Notes
20:8 he saw, and believed. When John “saw”—unlike the word used referring to Peter—the Greek indicates “looked with understanding.” He quickly understood that no other explanation than resurrection could account for the empty, yet intact, graveclothes. Therefore, he believed! This evidence of the empty tomb, which first convinced the beloved disciple, has later convinced multitudes of others, for it can never be explained in any other way. If Jesus had only swooned, or if the Romans or Jews had taken the body, it would soon have become known, and the spread of Christianity halted forthwith. But the body was gone, and would soon ascend to heaven, to remain forever inaccessible to Jesus’ enemies who would have liked desperately to prove that Jesus was dead.
