YOU Robert sadly strain at gnats to swallow camels. Jesus most certainly was referring to raising His body from the grave, when He spoke ot the Pharisees, the bible makes it clear so that anyone who can read can understand!
If you do not see that then I fear that what jesus said below may be true of you fully:
Matthew 6:22-34
The light of the body is the eye: if therefore thine eye be single, thy whole body shall be full of light. But if thine eye be evil, thy whole body shall be full of darkness. If therefore the light that is in thee be darkness, how great is that darkness!
For you to not clearly see Jesus was telling the Pharisees that He would raise His body from the grave concerns me much! It is a telling sign that the light in you is a great, great darkness.
God resurrected Jesus Ron as the Bible says at Acts 2:32
