"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." John 8:12
It's my favorite Halloween tale, how believers are like pumpkins...First, God picks you from the "pumpkin patch". All the outside influences/dirt of our former life must be removed. Old ways are washed away, and all things become new.
Then, He carefully removes all the “yucky stuff” (sin) from the inside. He changes us from the inside out by the Power of His Word. Seeds of doubt, hate, greed, and fear are removed and replaced with the seeds of faith, hope and love. After Jesus is invited inside, you begin to experience the changing power of God’s love in your life.
Next, He carves a new smiling face. With Jesus, who is called the Son of Light, lives inside of us, He shines through our life for all to see. Our countenance is changed by the power of His presence in our life, and it's evident to all.
Let your light so shine before men that they may be able to see your good works and glorify your Father, who is in heaven.
