What does Psalm 65:2 mean?

David reiterates that God hears prayer. This would encourage the people of Israel to pour out their hearts to the Lord in praise and in confession of sin (Psalm 65:3). God had spoken directly to Israel as His chosen people (Exodus 19—23), yet here David implies that the entire world of men will, eventually, come to acknowledge the Lord (Psalm 86:9; Romans 14:11; Philippians 2:10–11).

In Isaiah 45:22 the Lord calls upon all men, from the entire world, to turn to Him and be saved. He says, "For I am God, and there is none other." One of the reasons God formed Israel was to serve as a witness to the Gentiles (Deuteronomy 4:4–6; Isaiah 49:1–6). But the nation did not respond well to her calling. They failed to keep the Mosaic covenant, thus failing to be a tangible example of God's holiness and His goodness. When God commissioned Jonah to preach in Nineveh, Jonah rebelled. He boarded a ship bound for Tarshish (Jonah 1). Only God's disciplinary action that involved a large fish persuaded Jonah to obey the Lord (Jonah 2—3). Centuries later, Jesus commissioned His disciples to go and make disciples of all nations (Matthew 28:19). Romans 10:13 promises that "everyone who calls on the name of the Lord will be saved."
