God the Father is the sun
Your unfailing love, O Lord, is as vast as the heavens; your faithfulness reaches beyond the clouds. Psalm 36:5
In Him was life and that life was the light of men. The light shines in the darkness, but the darkness has not understood it.
This was the true light that gives light to every man who comes into the world. John 1:4,5 & 9
When Jesus spoke again to the people, he said, "I am the light of the world. Whoever follows me will never walk in darkness, but will have the light of life." John 8:12
God the Holy Spirit is the warmth
