I think it is of the essence to be able to connect to the notion there is something essentially positive about the universe. Call it God, Allah, “something”, the universe, love or music, happiness, progress… we need a mental understanding that what we perceive as “good” exists on a universal scale.
For some life makes sense just to be able to percieve, it is great, it is wonder. Love makes sense because gives you a fuller experience, it opens your system to experience, to enjoy, to connect and it offers you a compass in life.
But for a lot of us value needs an bigger all encompassing mental structure and we fear despair if it’s not there. If the only truth would be emptiness then what is the sense in living? Not believing in the positive side of our universe means a life without true meaning.
Problem with the word God is that it has a lot of bad publicity. A lot of innocent people were killed in the name of God. Morality can be manipulation. To me the term “axis of evil” is a horrible example of this.
