As such, it is in the darkness of its sin and face the eternal consequence of that sin. As the messenger of God who holds the truth of salvation in the Gospel message, we are light in comparison to the world. The people of the world live for themselves. The people who are reborn by the gospel message and Spirit-worked faith, are now children of God. While the sinful man lives for himself, the child of God lives to give all glory to God.
Faith Is the key element.
It has nothing to do with wealth, social standing, race, or even the exemplary lifestyle. Faith is what distinguishes the Christians from the world. The Holy Spirit brought us to faith through the preaching of God's Word. In the book of Acts we read that the disciples felt they could not help but to speak about the things they had seen and heard. They were shining lights because faith compelled them to share the truth.
