King Of Saints

And they sing the song of Moses the servant of God, and the song of the Lamb, saying, Great and marvellous are thy works, Lord God Almighty; just and true are thy ways, thou King of saints.  Revelation 15:3
Most people think of saints as people who have been beatified and honored by a church body because of their dedicated service to God.  But saints when it appears in the New Testament is a term for Christians.  Any person who has accepted Jesus as Savior and who follows Him as Lord of his life is a saint.  Christians as saints make up the church, the body of Christ.  
thus, Jesus’ name as King of Saints is similar to his title as Head of the Church.  He watches over His saints and energizes them through His Holy Spirit for the task of carrying out His work in the world.
In this verse from Revelation, the saints of God sing two songs-the song of Moses and the song of the Lamb.  These songs celebrate redemption and deliverance.  Just as Moses’ song celebrates Israel’s deliverance from Egyptian slavery (see Exodus 15:1-19), so the song of the Lamb rejoices in our deliverance from Satan and the bondage of sin and death.
