We, as human beings stake much of our happiness on sunlight. A Pastor at Concordia University Wisconsin spends some time looking this topic along side of 1 Thessalonians 5. We, as believers need live in the light of Christ and then reflect that light to this dark world!
Verses for Consideration:
1 John 1:7 ESV
But if we walk in the light, as he is in the light, we have fellowship with one another, and the blood of Jesus his Son cleanses us from all sin.
Isaiah 9:2 ESV
The people who walked in darkness have seen a great light; those who dwelt in a land of deep darkness, on them has light shined.
