LifeOfTheLay, what are you on about?

Father Awotwi said:

"This time fulfills me immensely as a missionary and a priest — opportunity for personal prayer and ministry." 

That is not statement about motive, about "serv[ing] to be fulfilled;" its an post hoc observation by this priest about the consequences of serving, that he as matter of fact finds fulfillment "in personal prayer and ministry."

Phrogge said:

 "Fulfillment is a good word to describe a chaplain's experience of serving the Gospel. It is a gift from God. Fulfillment happens in many professions, kind of an encouragement to keep on giving one's best." 

Again this is not a statement about motivation, about "serv[ing] to be fulfilled; its an observation that "serving the Gospel" as a chaplain can result in the divine gift of being fulfilled.

More importantly, an assessment of one's inner emotional experience as a guide to discerning the will of God is a fundamental principle in all deep Christian spiritualities
