It's every person's right to believe or not believe in God who created the heavens and the earth and all that goes with it. But, no opinion will make God disappear or diminish who he is.
C.S. Lewis said, “A man can no more diminish God's glory by refusing to worship Him than a lunatic can put out the sun by scribbling the word, 'darkness' on the walls of his cell.” (source here)
“In the beginning was the Word, and the Word was with God, and the Word was God. He was with God in the beginning. Through him all things were made; without him nothing was made that has been made. In him was life, and that life was the light of all mankind. The light shines in the darkness, and the darkness has not overcome it.” John 1: 1-5 (NIV)
“I am the Alpha and the Omega,” says the Lord God, “who is, and who was, and who is to come, the Almighty.” Revelations 1:8 (NIV)
Have a wonderful Sunday!
