Alexander Solzhenitsyn was a prisoner in a Soviet prison in Siberia. He became so weak and discouraged that he wished he would die. The guards would beat and usually kill anyone that stopped working. He decided to stop working so that the guards would kill him. As soon as he did so, another Christian drew a cross where Alexander could see it.
Alexander said that he was encouraged by remembering that God gives hope and courage. He decided to continue working because of a Christian who cared too much to let him give up.
