Proverbs 4:18 The path of the righteous is like the morning sun,
shining ever brighter till the full light of day.

I watch the Sunrises in a different way sometimes.  I watch with the sun to my back.  I am always amazed as the detail of the landscape is revealed.  Shapeless and gray turning brilliant and beautiful as trees became visible and the colors burst forth.  I never once turn to look where the sun is in the sky, I just kept watching in amazement as more and more light brings  out more and more detail.  I get the feeling this is how the light of God will shine in heaven.   We will know the source of the light and the details of heaven will be revealed in that light.

Rev 22: 5 There will be no more night. They will not need the light of a lamp or the light of the sun, for the Lord God will give them light. And they will reign for ever and ever.
