“And the angels which kept not their first estate, but left their own habitation, he hath reserved in everlasting chains u nder darkness unto the judgment of the great day.” Jude 6
Lucifer and a third of the angels of God became the very first apostates – those who were once with God then departed (1 Tim. 4:1-3). The angels were not “kept” against their own agreement or will. The same is true for humans God saves. They are never forced to remain in relationship with the LORD and if they depart (apostatize), eternal damnation awaits.
It’s a historical, biblical fact that Lucifer and a third of the angels that were previously of God and in His holy Heaven, decided to rebel and were thrust out for good – they fell from grace.
Lucifer, like all the angels of God, was given a choice. If such were not the case, how would one-third of the angels have departed from the LORD and two-thirds freely chose not to become apostate? From this we know the angels, a distinct class of God’s creation, have free will also. See Revelation 12. Lucifer was in the grace of God, holding one of the higher offices in Heaven, until he volitionally chose to sin. Jude even warns us – human beings – using the fall or apostasy of the angels in Heaven, warning us not to do as they did. They are eternally lost after having been in the grace and Heavenly abode of the Almighty.
“Thou wast perfect in thy ways from the day that thou wast created, till iniquity was found in thee.” Ezekiel 28:15
Judas, chosen by the LORD and promised an eternal throne in Heaven (Matt. 19:28), wasn’t faithful to the end, so he fell away into sin and is now in hell (Acts 1:25). Judas, like Lucifer, was clearly (at the time Jesus chose him as one of His very twelve) in right standing with Jesus “till iniquity was found” in him (Ezek. 28:15). Recall that like the arch enemy of mankind, Judas fell by his very own transgression which is always the result of choosing to be out of fellowship with the LORD of all creation (Acts 1:25) . Beloved, any time we have fallen from the grace of God, it has been the direct result of our own transgression. May God be praised that He is “ready (postured) to forgive” as we turn to Him in repentance (Ps. 86:5, 15).
