Not "a lot."
Jesus' sacrifice on the cross means the most to me of anything this world has to offer. And the best part is . . . He didn't stop with the cross. He rose again, and His spirit is within me. Jesus walks and talks with me everyday.
Someone once told me that if anyone doubtfully asks "how do you know your Jesus is the real messiah . . . not Mohammed or Buddha or some other prophet?" the best reply possible is "because He's the only one who died . . . but rose again!" Jesus conquered the grave so you and I may live eternally with Him in Paradise.
I cannot think of anything that means more.
