Oh boy, finally, a thread where my esoteric knowledge can shine.
So the reason he has a scythe is because he's Saturn, the scythe is for cutting Uranus's balls off.
Of course Zeus buttfucked him to death but we still have Saturday representing time, cycles, and of course, death.
But here's where shit gets real fucky.
>I am the First and the Last.
Treat that like a riddle and you will see God can only be....time!
As if anything existed before time (matter, energy, thought) it would rely on time to progress to make a thing happen so it could not have been "first".
Of course God is also Zeus/Jupiter as well as 5 other things besides Jupiter and Zeus but all that to say, the Grim Reaper is cool and even makes a guest appearance in the Book of Revelation.
Guess who he looks like? Not a skelly.
