What if the light at the end of the tunnel is a train?

I hate to be pessimistic, but sometimes it's hard not to be. It just seems like when I think I've got my "stuff" together something I do or have done creeps up and stings me again. Most of my issues stem from the fact that when it comes to the almighty dollar I seem to be unable to change my habits. I guess if you think about it, if it is like a dark tunnel with a light at the end, you're bound to trip over something once in a while before you reach the end. I think the secret is to continue to get back up. Not only to get back up but to keep right on going toward the light at the end. Maybe the tunnel is the journey. The things we trip over along the way are our sins, our earthly stumbling blocks.

After all it does say in John 18:12 "When Jesus spoke again to the people, he said, "I am the light of the world. Whoever follows me will never walk in darkness, but will have the light of life."

I see through the progression of this post that my God has comforted me. I went from feeling pessimistic about the world to understanding that the light at the end of the tunnel isn't a train... It is "The light of the world" Jesus Christ.
