FALLEN ANGELS is a common term used by almost everyone, and a verse in Jude seems to relate to this. We probably will not cover every verse of scripture that might answer all of our questions concerning this subject, but this is one into which we should look. "And the angels which KEPT not their first estate, but LEFT their own habitation, he hath reserved in everlasting chains of darkness unto the judgment of the great day." (Jude 6). The Concordant Literal translates these two verbs (kept & left) as KEEP and LEAVE, for they are in the aorist active form. They are not in the indicative past tense. This would, therefore, indicate those being held in darkness with unbreakable chains are the ones who have and are PRESENTLY not remaining in the place God had placed them in. These angels, rather MESSENGERS (Grk), I believe to be none other than M-E-N today who fall into and submit to the same temptations Sodom and Gomorrah had lusted after. Verse 7 speaks of this, and think about it as you read it -- angels are not tempted with fleshy lusts, however, men are. Therefore, we believe Jude is referring to men who are the messengers rather than spirit beings, and because of their perverted desires they are held in darkness (strong delusion to believe a lie, II Thes. 2:11-12) until the day of judgment.
