I haven’t noticed my own morality in years, but I tried the thought experiment that just as I did for “if God is a fact” to feel his presence, I did the same for “I’m going to die”.
Suddenly, so many things feel stupid.
Before I die, whenever that is, I want to make my family happy.
Death is sad, and I don’t want it to be worse by having to leave them knowing that they aren’t happy people.
The ultimate form of self control is submission, but I choose to submit myself to objective morality before anyone who claims to fulfil the role of authority for sharing insight into that morality that they themselves are subservient to, including God.
