1 Peter 2:9
"But ye are a chosen generation, a royal priesthood, an holy nation, a peculiar people; that ye should shew forth the praises of him who hath called you out of darkness into his marvellous light:"
God says about the Christian, "Ye are the light of the world. A city that is set on an hill cannot be hid." (Matthew 5:14) God says in the verse above that He has called us "out of darkness into his marvellous light." When the Christian got saved, they were called out of the darkness of Satan's power, immorality, powerless living, no hope and eternal punishment. When a person gets saved, they are saved to eternal life, a relationship with God, a blessed hope, an empowered life and a life of purpose.
