7 “For the sea is His and He made it”. For the sea is this world, but God made also the sea: nor can the waves rage save only so far as to the shore, where He has marked their bounds. There is therefore no temptation, that has not received its measure....“And His hands prepared the dry land.” Be thou the dry land: thirst for the grace of God: that as a sweet shower it may come upon you, may find in you fruit. He allows not the waves to cover what He has sown. “And His hands prepared the dry land.” Hence also therefore let us shout unto the Lord.
