Some people say that Jesus body was stolen but they can't answer logically as to why anyone would steal his body because no one at that point knew what Jesus was doing. They didn't know he was going to rise again in three days. It wasn't until he appeared and then later the Holy Spirit came to the disciples where they finally understood the big picture of his sacrifice and the New Covenant that God made.
As for me, I'm a believer. I believe he suffered, died, and was buried and on the third day rose again in accordance with the scriptures. Thank you Jesus!
