Say unto them, As I live, saith the Lord God, I have no pleasure in the death of the wicked; but that the wicked turn from his way and live: turn ye, turn ye from your evil ways; for why will ye die, O house of Israel?
Ezekiel 33:11
God does not take pleasure in destroying the wicked. He truly wishes for all to repent of their wicked ways and to be reconciled back unto God. God made all of His creatures, including angels and mankind, with the purpose and intention of having a relationship with them. God made all of creation with the purpose of having a family of His own. If one of His children stray away from Him, He will desire for that child to return to Him, no matter what wickedness that this child has done. This is the story of the prodigal son. God will be waiting with open arms to one of His children who strayed away but came back. God is willing to forgive whatever wickedness His child has done.
This applies to the fallen angels as well, who are also children of the Most High. Because of God’s infinite mercy, He is willing to forgive even the fallen angels, if only they truly repent. God is willing to wipe away thousands of years of sin and to restore each fallen angel to his former glory, if only they repent. Yes, He is even willing to forgive Satan, if only he repents. However, Satan will never repent because of his own pride, since repentance means admitting you were wrong and that God is right. If Satan were to admit that he was wrong, he would have to admit he was wrong to everyone that he misled. Satan has too much ego to let this happen, and so he is willing to be punished in Hell rather than to admit he was wrong about everything.
If one believes that God won’t be willing to forgive the fallen angels, this means believing that God is not infinitely merciful. In that case, one is underestimating God’s infinite mercy. God is willing to forgive everyone, but only if they truly ask Him for forgiveness.
There are many passages in Scripture which show that God extends His mercy to everyone, such as in 2 Peter 3:9:
The Lord is not slack concerning his promise [regarding the day of God’s judgment], as some men count slackness; but is longsuffering to us-ward, not willing that any should perish, but that all should come to repentance.
2 Peter 3:9
God takes no pleasure in the destruction of the wicked. His desire is for every wicked individual to repent of their ways and to return to God. God is patient, giving time for the wicked to repent before God is required to put an end to the wicked due to His perfect justice.
There is no reason to think that this does not also apply to angels that have fallen since they are God’s children as well. God wants each and every sinner to come to repentance before Him and to be reconciled back to Him; to rejoin God’s family. To think otherwise is to believe that God actually desires for some of His children to be sent to Hell. This is not so. God does not desire for anyone to end up in Hell. However, due to their own freewill, sinners choose to be separated from God by choosing a life of sin. If they refuse to repent, this choice ends up causing the ultimate separation from God: of being sent to Hell.
