The answer is: A prophecy of the future kingdom after the return of Christ

Psalm 72 - Often viewed as a messianic psalm, it describes the ideal reign of a righteous king whose rule brings justice and peace. This vision aligns with prophecies in Isaiah (Isaiah 9:6-7) about the coming Messiah, emphasizing God's ultimate plan for restoration and unity through Christ.

Psalm 72 is often celebrated for painting a vivid portrait of a ruler who epitomizes justice, equity, and peace. While conventional interpretations may view this psalm as a prophecy of Christ’s reign, it can also reflect timeless ideals of governance applicable to any leader striving for fairness.

Historically, this psalm connects deeply with King Solomon, traditionally associated with wisdom and prosperity. Its language mirrors the grandeur one might find in royal dedications or petitions made for rulers. A fun tidbit: ancient Jewish wisdom literature often called for kings to be compassionate, so Psalm 72 fits perfectly within that context, spreading ideals of 'kingly righteousness' well beyond just one figure through history.

Psalm 72 also sheds light on the sweeping aspirations for communal harmony. The phrase “Let the mountains and hills bear peace” underlines a poetic vision of nature coming alive in support of justice—something profoundly resonant today. Isn't it fascinating how these IPOs—ideal principles of order—have preserved their relevance?

Interestingly, echoing the earlier verses in Isaiah around the messiah's birth, both scriptures reveal wider hopes rooted in liberation and unity—qualities every social movement today still strives for. So it’s not just about pointing to a distant messiah; rather, it’s an illuminating call towards fostering a world marked by altruism and equality here in our midst. This dual focus inspires not just a future promise, but one we can contribute to right now.
