Se pou nou renmen tout bon vre...it is for us to love (all good true)??? I struggle only knowing the literal translation sometimes...what it this saying in the context of the Creole language? Mesi Mandaly!!

Dakò :)

Se pou ... denotes obligation, duty, requirement
example:
Se pou ou vini wè mwen. 
You must come see me.

Se pou yo netwaye kay la anvan yo pati.
They should clean the house before they leave.

notice how the subject is placed after SE POU.

Tout bon vre means for real, for good, genuinely, truly

Se pou nou renmen tout bon vre...
You must love for real... (literally)
