Katharine Lee Bates is a highly educated English professor, writer, and social reform advocate born in Falmouth, Massachusetts. Traveling cross-country to teach in Colorado, she is deeply moved by the scale of the American natural environment, which inspires her to write her most famous poem. Beyond her poetic achievements, she is a fierce advocate for marginalized groups. She weaves her desire for social progress and divine guidance into her patriotic verses, viewing her country as a flawed work in progress that requires spiritual help to match its physical beauty.

In the context of the poem, God is the divine protector and guide of America. Rather than being used as a prop to justify the country's manifest destiny or inherent superiority, God is addressed in a prayerful manner. The speaker asks God to mend the nation's flaws, refine its wealth, and grant it grace, relying on this divine presence to help the nation live up to the sublime beauty of its natural surroundings.
