Our world is getting darker and darker. Jesus Christ is the only true light.
"Do everything without grumbling and arguing, so that you may be blameless and pure, children of God who are faultless in a crooked and perverted generation, among whom you shine like stars in the world."
Jesus is the only true light, but as believers we are to be "shining lights". We are to Shine In a Dark World. As believers we are to walk and live a lifestyle that is so distinct from the worlds darkness that it like a star shining in the midnight sky.
"Holding firmly the message of life. Then I can boast in the day of Christ that I didn't run in vain or labor for nothing."
The message of the word is an introduction to life. This world thinks they are really living and that pleasure, possession, popularity, and promotion is what life is all about. God's Word not only tells you where you can find life, but how you can give your life to him.
Till Christ comes our world will get darker and darker but as a Christian we are to be the shining light so that others might find Jesus Christ.
