The very best blessing will be to exist in the presence of our Father God and our Lord and Savior Jesus Christ. No need for the sun because the Father and Son will be our eternal light. Revelations 21st chapter:
"God said, See I am making everything new! Write this down, for these words are trustworthy and true. It is done. I am the Alpha and the Omega, the Beginning and the End. To the thirsty I will give water without cost from the spring of the water of life. Those who are victorious will inherit all this, and I will be their God and they will be my children. But the cowardly, the unbelieving, the vile, the murderers, the sexually immoral, those who practice magic arts, the idolaters and all liars—they will be consigned to the fiery lake of burning sulfur. This is the second death.”
