Very good points, everyone.
When I was in school, we had to watch the film Schindler's List. It was a movie about the holocaust and how a Austrian-German businessman, Oskar Schindler, saved the lives of over 1,100 Jews during the Holocaust. The film is very graphic depiction of the horrific events during that time in history. It is difficult to watch...and many of the haunting images are almost impossible to erase from your mind.
At the end of the film, there is a scene in which the war is coming to a close. Oskar Schindler is about to go into hiding. Many of the Jews that he saved gather to bid him farewell. They present him with a ring and a note signed by those that he saved.
Schindler is deeply moved by this act. However, the realization of what he did is pressing -- particularly the fact that he could have done so much more! He points to his car and pin, saying that the money could have been used to save others.
I know that many will not think that this is a very "spiritual" anecdote, but I think that this sentiment speaks truth in spiritual matters too.
When we all stand before God on that Day, will the realization of how we could have helped others overwhelm us? Will the people that we encountered in life point at us and wonder why we never told them the truth? Even if we didn't "preach," did we live our lives in a manner that made us a Living Epistle that drew men TO our Lord or turned them away?
In one of my favorite messages here on SermonIndex ("Holy Ground" by David Wilkerson), we are struck by the realization of our great potential in this life -- for good or evil. We can draw men to Christ or be a stumbling block that turns them away. How dreadful to think of the responsibility for which we are entrusted! Keith Green used to say that this generation of Christians is responsible for this generation of souls. How true that is!
I agree with sister Ginnyrose that no one will ultimately be without excuse. After all, "the Heavens declare the glory of God." I have met an indigenous pastor from the Tarahumara tribe deep within the rugged, pine-covered mountains of the Sierra Madre Occidental in Chihuahua, Mexico who came to Christ without ever having heard from or met another Christian. So, someone can find the Truth via the measure of faith planted within him.
Still, there is a great responsibility that we have to the people of this world. I can't help but think of the Parable of the Talents -- and how we will be called into account for all of the "talents" (or opportunities) that we have been given.
May God help us to share the Good News with those around us!
