There's a great story about Alexander Solzhenitsyn, the Russian writer who spent years in a Siberian prison. At one point he had become completely discouraged and decided to give up and die. His plan was to stop working out in the field, to lean on his shovel, and wait for the guards to come and beat him to death. However, when he stopped, another prisoner reached over with his shovel and quickly drew a cross at his feet, then erased it before a guard could see it.
Solzhenitsyn later said that his entire being was energized by that little reminder of the hope and courage we have in Christ. He found the strength to continue because a fellow believer cared enough to remind him of our hope.
