What does Psalm 65:7 mean?

David continues to describe God's might using examples from the environment. Oceans and seas are among the earth's most obvious examples of the power of nature. Mountains are symbolic of power and stability, implying that the power of their Creator is even greater (Psalm 65:6). Massive bodies of water move and change beyond human control. God's ability to regulate the awesome power of the ocean implies His omnipotence. The raging of human nations, often against God or against His people, is sometimes compared to stormy seas and waves (Isaiah 17:12). Ultimately, these rebelling nations will be defeated and made silent (Isaiah 17:13).

Jesus, by whom everything was made (John 1:3), demonstrated His power to quiet the raging waves on the Sea of Galilee. One evening, after a long day of ministry, Jesus was asleep in a boat. Suddenly a great windstorm arose and the waves started to fill the boat. The terrified disciples, who were also in the boat, thought they would die. They awoke Jesus. He then commanded the wind and waters to be still. At His order, the wind ceased and a great calm followed (Mark 4:35–41).
