Once you're in a kind of revealed religious tradition, you wind up having to explain how the things said about God in the Bible or the Qur'an or whatever religious text you're dealing with, why these statements are true.

Assuming there is an intellect, we're clearly not this universal intellect or we would know it. So that's one function of soul.

We do have intellects and Plotinus controversially thought that even though we might not be aware of it, our souls are always connected to the intellect. They never fully descend as he would put it.

The forms are part of the mind, or really are the mind, they're just the contents of this universal night.

In fact Plotinus thought not only that soul in general is eternal so that you always have soul, but he thought that each person's soul is eternal.

Sometimes clichés are true.

In fact one of the things about Plotinus is that he maybe not singlehandedly, but I think more than anyone else, killed off the variety and dissension among the philosophical schools of antiquity.
