Question: Pastor Younce, can you tell me why God created the Devil?
Answer: No, I cannot! Because God did not create the Devil; neither did God create man as a sinner. In Ezekiel 28 we have the word of God concerning the literal king of Tyre; but it becomes a picture of the Devil, who deceived the king of Tyre. Thus, the king of Tyre personifies the Devil. In Verse 12, Lucifer was "created full of wisdom and perfect in beauty." In Verse 14, he was the "anointed cherub." Verse 15 says,
"Thou wast perfect in thy ways from the day that thou wast created, till iniquity was found in thee".
Isaiah 14 tells us why he sinned.
"How art thou fallen from heaven, O Lucifer, son of the morning!... (12a) For thou hast said in thine heart, I will ascend into heaven, I will exalt my throne above the stars of God: I will sit also upon the mount of the congregation, in the sides of the north: (13) I will ascend above the heights of the clouds; I will be like the most high." (Isaiah 14:12-14).
Lucifer wanted to take over the throne of God.
Lucifer persuaded one-third of all the angels to follow him (Revelation 12:4). From this time on he is called "Satan" (meaning "Adversary"), "Devil" ("Accuser"), "Serpent," "Dragon" (descriptive of his character) and etc. (Revelation 12:9)
God’s reaction to his rebellion "Thou shalt be brought down to Hell." (Isaiah 14:15). Matthew 25:41 tells us, "Depart from me, ye cursed, into everlasting fire, prepared for the devil and his angels" His final end is given in Revelation 20:10,
"And the devil that deceived them was cast into the lake of fire and brimstone...and shall be tormented day and night for ever and ever."
God’s plea is
"Believe on the Lord Jesus Christ and thou shalt be saved"
...saved from spending eternity in Hell with Satan.
