     Maybe you have ever seen a cross. A cross can be a piece of jewelry or an image in a painting. But do

you know the cross is a very popular symbol for Christmas?

     It came from the story of Jesus' death on the cross two thousand years ago in Jerusalem. Jesus was

Jewish,and at that time Jewish people were under Roman rule. Jesus was badly punished because he declared

to be the Son of God and the King of Jews. Surely, the Son of God could have saved himself from the death!

But the Bible says that Jesus had a reason to die that day. It was in God's purpose that it would happen.

     Christians call the day that Jesus died "Good Friday". At first, it is hard to understand how a terrible day

could ever be called good. Well, the story does not end there. Jesus died and he was buried. But three days

later, Jesus was alive, and the whole world was changed.

     Today, Christians everywhere remember this important time. They celebrate Easter. Easter is the day that

Jesus rose from the dead. After his death on the cross,Jesus' body was placed in a tomb. On the third day

from then, God raised him from the dead. Jesus stayed on earth physically for several weeks. Many people

saw him. Easter is the happiest time of year for Christians because they believe that Jesus had victory over

death and evil and that now he lives with God the Father in heaven. But before celebrating Easter, Good Friday

should be remembered. Jesus died a horrible and painful death. He suffered, though he did noting wrong.

Christian believe that Jesus was God's substitute (代表) for humans, because humans all do wrong. He died

because of humans and he died for humans. 

     Christians often wear crossed around their necks of hang them in their homes because they believe it is a

very important sign. The cross helps them remember how much God loves them. It helps them remember

how much his Son had to suffer. Seeing a cross always makes them think of Jesus' death, and what it means.
