Revelation 15

John sees another vision of events taking place in heaven.  Angels carrying bowls of God's judgment prepare to pour out His wrath upon the earth.  Before they do this, God is praised for His holiness, mightiness, justice and worthiness of worship.  While God may punish the earth, He is just for doing so.  It is His creation and He may deal with it in whatever way He desires.  His actions prove that He has the authority and control over the universe.
