This reminds me that the Easter story is basically in two parts. The first is when Jesus the Son of God is crucified, (executed like a common criminal), as a sacrifice, so that we might be forgiven and showing Jesus on the cross is a reminder of this. The second is when Jesus rises from the dead so that we might have everlasting life. The empty cross signifies this. That is why I especially like this statue of Jesus in the Meditation Garden at Graceland, shown above. (It was initially the headstone of Elvis' mother, Gladys grave in Forest Hills Cemetery in Memphis). The statue shows Jesus very much alive with open arms welcoming us, but in the background is the cross to remind us of what He did for us.
God bless you.
