A Question Regards ... Latin Grammar

Alternative to the Gerund

Africanus omnibus salutem dicit,

Seeing as there is NO gerund for the verb esse, how would the following phrase be rendered:

For the sake of doing good

to do good: prosum, prodesse, profui

An example of the gerund construction that I had originally thought ideal for this follows:

gratia discendi = for the sake of learning

any help would be much appreciated.
