According to Revelation 22:16
16 I Jesus have sent mine angel to testify unto you these things in the churches. I am the root and the offspring of David, and the bright and morning star. (KJV)
We see Jesus is called the bright and morning star.
Now let’s look at Isaiah 14:12
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! (KJV)
We see here that Lucifer is the son of the morning and fell from heaven and weaken the nations. This person was not Jesus, Jesus never fell from heaven.
18 And he said unto them, I beheld Satan as lightning fall from heaven. (KJV)
Jesus came from heaven to earth as a baby , grew up as man, died as man and is now in Heaven seated at the right hand of the Father. If you read Isaiah 14:12-19 you will see it was Satan that fell from heaven. So Lucifer is another name for Satan
But now the what the..
Let us look at bible version that is the number 1 version in the world the NIV, let us see what it says for Isaiah 14:12
How you have fallen from heaven,
morning star, son of the dawn!
You have been cast down to the earth,
you who once laid low the nations! (NIV)
Now can you see the (what the..) The NIV is calling Lucifier the morning star, but according to Rev 22:11 Jesus is called the Morning star, from the NIV (Rev 22:16)
16 “I, Jesus, have sent my angel to give you[a] this testimony for the churches. I am the Root and the Offspring of David, and the bright Morning Star.”
So we now have the Number 1 bible in the World calling Jesus Lucifier, to me this is unthinkable. If you have an NIV, my advice is to change versions, find one that places Jesus as the savior of the world. Jesus is King of Kings and Lord of Lords
