The earliest Christians believed in the Resurrection not because they couldn’t find a dead body but because they found a living Christ. There is not one recorded instance of denial of the Resurrection among the Apostles or the ~500 other witnesses who saw the risen Christ. They had compelling reasons to recant, even unto their deaths. Not one. (Note 1)
If Jesus rose from the dead, then you have to accept all that He said. If He didn’t rise from the dead, then why worry about any of what He said? The issue on which everything hangs is not whether or not you like His teachings, but whether or not He rose from the dead. (Note 2)
