I wasn't sure where this thread belongs, whether in Idioms & Sayings or Vocabulary, and sorry if it's misplaced here.
How do people from the various countries represented in Tomísimo say "Lord willing" either at the beginning or the end of a statement wherein they commit themselves to do something? I've heard the following, at least from Mexicans and Costa Ricans:

Dios primero
Primero Dios
Dios quiera
Si Dios quiere
Si Dios lo permite
Dios mediante

Are there others as well? Which ones are the most widely-used?
