What do the Gospels tell us? They tell us of the ministry of Jesus.
Amen, with an addendum I will tie back to his main point;
One remarkable fact about Jesus' "ministry" was how short it was.
Look at the other world religions. Confucius, Gautama (Buddha), Mohamed, all had long lives of teaching & conquest, backed by money.
Jesus ministry was only long enough to establish who he was.
His true purpose was not his teaching, but to die & rise again.
Three historical bedrock facts led to Christianity's explosion:
(1) Jesus really was executed by the legal authorities by crucifixion;
(2) his followers were absolutely convinced he had come back from the dead;
(3) within 3 years, Paul, an opponent, converted after being convinced he had a real encounter with the risen Lord.
Without denigrating Jesus' teachings, they are secondary.
Saying it another way: his teachings are very important, but pale before his Resurrection, which validate the teachings.
(Maybe one reason he didn't spend several decades teaching & writing it down, is that the Jewish scriptures were already there.)
Back to Williams' point:
Note that while the resurrection gives importance to His/our physical bodies, again, no mention of its appearance, other than the trophy pierced hands, feet, side.
