Concerning what did Christ tell us not to marvel?

Answer

"Marvel not at this: for the hour is coming, in the which all that are in the graves shall hear His voice, and
shall come forth; they that have done good, unto the resurrection of life; and they that have done evil, unto
the resurrection of damnation." John 5: 28, 29.
