Revelation 1:5
And from Jesus Christ, who is the faithful witness and the first begotten of the dead and the prince of the kings of the earth.Unto him that loved us and washed us from our sins in his own blood.The reason that Christ is the "first begotten" from the dead is because, while others (i.e. Lazarus) were raised to life they died again, he was raise from the dead to immortality-never to die again! This is way Christ should be the first that should rise from the dead (Acts 26:23)...and why He only hath immortality (1 Timothy 6:16). It is important to note that Christ is called "the first begotten" or "the firstborn of the dead". Other times He is called "the only begotten". The term "only begotten" refers to His incarnation, whereas "first begotten" (or firstborn) refers to His ressurection. See Hebrews 1:6, Colossians 1:15 and Colossians 1:18.The Lord Jesus Christ is also called the prince of the kings of the earth. This refers to the future when the Prince of Peace (Isaiah 9:6) returns as the King of Kings and Lord of Lords (Revelation 19:16). This glorious event will be the fullfillments of scripture in Psalm 72:8.
