Life is made up of mountaintops, valleys, clear paths and tunnels. We all walk through the valley of the shadow of death sometimes, and we all see glory from the top of mountains other times.
When you look at life this way, you begin to see it as an adventure, and just like most adventures, not everything goes right all of the time. You have to overcome obstacles, and you have to look for the light at the end of the tunnel to keep pressing on sometimes. It's that little light that gives hope.
Keep pursuing the light at the end of your tunnel, no matter how far away it may seem. Press toward the light in life because it's the light that casts out darkness.

Cliff's Note: Resist the dark and pursue the light.
