Around the year 2008, atheists in the UK and the US began promoting bus signs with various anti-religious slogans, one of which read “There’s probably no God, now stop worrying and enjoy life.”
This slogan succinctly sums up the looming problem with religion: only good boys and girls go to heaven. God, therefore, becomes a source of worry; of anxiety. How do I know if I’m good enough? With this omniscient authority figure frowning down from heaven on high, constantly judging my every action, ready to condemn, his laws are an oppressive burden that rob life of any enjoyment it might otherwise offer.
Consequently, atheism becomes a source of relief. Freed from the horror of this judgmental God, a person may now act as they please without fear of consequence.
