What term describes a person who is praying humbly for something?

The term "supplicant" refers to an individual who earnestly and humbly requests something, often in a context of prayer or earnest appeal. This word is closely associated with the act of supplication, which means to seek something from a higher authority or power, typically characterized by humility. In religious or spiritual contexts, a supplicant might be someone who approaches God or a deity with sincere petitions or requests.

The other terms, while having their own distinct meanings, do not convey the same sense of humility and earnestness in seeking something from a higher power. An advocate is someone who supports or defends a cause, a proponent is a person who advocates for a particular idea or proposal, and a benefactor is someone who provides help or support, especially financial, to others. These roles do not inherently involve the humble act of prayer or supplication, making "supplicant" the most fitting term for describing a person in a state of humble prayer.
