Is belong a possessive pronoun

The word "belong" is not a possessive pronoun. However, a word that indicates ownership by replacing a noun (or a noun phrase) in a sentence is a possessive pronoun. For instance, possessive pronouns include: mine, yours, his, hers, ours, and theirs.

I would say no..

Explanation:

I would say no because possessive pronouns show ownership.  The possessive pronouns are my, our, your, his, her, its, and their. There's also an “independent” form of each of these pronouns: mine, ours, yours, his, hers, its, and theirs. Possessive pronouns are NEVER spelled with apostrophes.

Ownership is indicated in the sentence. For example, take this sentence as an example:  That is his dog.

The pronoun HIS shows that the puppy belongs to him. This shows ownership in the puppy belonging to him.

in paragraph 6 of "sinners in the hands of an angry god" by jonathan edwards, he talks about how doing good things alone will not save men from going to hell because they're at the mercy of the will of god. "spiritual reform" provides men with a false sense of safety.
