Psalm 77:16-19 says, "16The waters saw thee, O God, the waters saw thee; they were afraid: the depths also were troubled. 17The clouds poured out water: the skies sent out a sound: thine arrows also went abroad. 18The voice of thy thunder was in the heaven: the lightnings lightened the world: the earth trembled and shook. 19Thy way is in the sea, and thy path in the great waters, and thy footsteps are not known."
And Psalm 93 says, "1The LORD reigneth, he is clothed with majesty; the LORD is clothed with strength, wherewith he hath girded himself: the world also is stablished, that it cannot be moved. 2Thy throne is established of old: thou art from everlasting. 3The floods have lifted up, O LORD, the floods have lifted up their voice; the floods lift up their waves. 4The LORD on high is mightier than the noise of many waters, yea, than the mighty waves of the sea. 5Thy testimonies are very sure: holiness becometh thine house, O LORD, for ever."
Recently Japan experienced tremendous devastation due to a tsunami. This link goes to a video of that tsunami. In this video, one can see the mighty power of the sea. Yet, the LORD on high is mightier than the mighty waves of the sea.
