You are Children of the Light
The Holy Spirit, who dwells in your heart, will perfect and establish you in your faith. He will also strengthen and settle. The light of the world is Jesus, and He has also made you become the light.
But you, brethren, are not in darkness, so that this Day should overtake you as a thief. You are all sons of light and sons of the day. We are not of the night nor of darkness. Therefore, let us not sleep, as others do, but let us watch and be sober. For those who sleep, sleep at night, and those who get drunk are drunk at night. But let us who are of the day be sober, putting on the breastplate of faith and love, and as a helmet the hope of salvation. (1 Thessalonians 5:4-8)
