1. Psalm 19 speaks of the heaven's proclaiming the glory of God - and the sun's part in that is to be like a bridegroom moving through the sky. That's not abstract power, it's LOVE. Look at the sky and see the love of God.This is God's world and it is singing out the gospel. What can you see?
2. The gospel pattern is that the Triune God sends the Son into the world as The Light who shines in the darkness. The darkness tries to overcome the light but cannot. The moon shines at night to hold back the darkness, and the sun does so in the daytime.
3. And, Jesus died in the dark and rose in the morning. The end of the day proclaims the death of Jesus, the new morning proclaims the mercy of God - it proclaims the resurrection.
