Psalm 2 is a celebration of the unquestionable supremacy of God and his Messiah over all the rebellious forces of humanity. Not only is this the message of the Psalm’s content, it is even embedded in the Psalm’s concentric structure.
Psalm 2 describes an idealized Israelite king as God’s Messiah. Jesus radically reinterpreted this idealization when he chose to exercise his Messianic authority through service, self-sacrifice, and trust in God. The Church, as co-heirs with Christ, now share in the Messianic privileges and responsibilities.
