(1) Just about everybody knows the word "Lucifer" as another name for Satan. The word "Lucifer" is found one time in the King James Bible.
Isaiah 14:12 How art thou fallen from heaven, O Lucifer, son of the morning! how art thou cut down to the ground, which didst weaken the nations!
(2) But what about the NIV? The word "Lucifer" is clean, bald-headed gone and now this creature is identified as the "morning star". Lucifer is the "morning star" in the NIV.
How you have fallen from heaven, O morning star, son of the dawn! You have been cast down to the earth, you who once laid low the nations!
(3) So we know that in the NIV the "morning star" is a negative, evil figure. Right? He was fallen from heaven. He was cast down to the earth. Can we find the "morning star" anywhere else in the NIV? Yes! The following passages in the NIV show the "morning star" as Jesus Christ! But the NIV just called the fallen creature of Isaiah 14:12 "morning star". Lucifer AND Jesus are ONE in the NIV! Lord have mercy, Jesus! Help me, Lord.
NIV: Revelation 22:16,
"I, Jesus, have sent my angel to give you  this testimony for the churches. I am the Root and the Offspring of David, and the bright Morning Star."
NIV: 2 Peter 1:19,
And we have the word of the prophets made more certain, and you will do well to pay attention to it, as to a light shining in a dark place, until the day dawns and the morning star rises in your hearts.
