Lucifer was a creature created by God. Jesus is God. Lucifer rebelled and was banished and condemned for eternity.
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! 13 You said in your heart, "I will ascend to the heavens; I will raise my throne above the stars of God; I will sit enthroned on the mount of assembly, on the utmost heights of Mount Zaphon.[1] 14 I will ascend above the tops of the clouds; I will make myself like the Most High." 15 But you are brought down to the realm of the dead, to the depths of the pit.
