Still doubting?

Today I read a verse that I never noticed before.  It's at the end of the book of Matthew.  After Jesus was crucified, dead, buried and resurrected He appeared to his followers in Galilee.  Verse 17 says, "When they saw Him (Jesus), they worshipped, but some doubted."  Can you imagine seeing someone alive who had been dead?  They couldn't deny that He was standing in front of them, but they were so dumbfounded by what they couldn't understand that they doubted what they were seeing.  In John chapter 20 Thomas doubted because he had not yet seen the risen Christ.  After appearing to Thomas, Jesus said, "Because you have seen me, you have believed; blessed are those who have not seen and yet have believed."  Thomas doubted because he had not seen.  I know a lot of people like that who what to see proof before they will believe, but according to Matthew 28:17 it is possible to see Jesus standing before you and still doubt.  Some people do not have enough faith to see evidence of the risen Christ when it is right in front of them.  May I not be one of them.
