Does Lucifer have access to heaven?
Currently Lucifer does have restricted access to Heaven. In Job 1:6 we read: “Now there was a day when the sons of God came to present themselves before the LORD, and Satan came also among them.” The “sons of God” or angels were summoned by God to appear before Him, and Satan was among them. Satan was bringing accusations against Job, stating that he only worshiped God because God blessed him with wealth, and when Job refused to curse God after his wealth was taken, Satan again appeared before God and stated that is was only because Job had his health that he worshiped God. Satan continues to accuse the brethren up to this day, and until the mid-point of the Tribulation where we read in Revelation 12:10: “And I heard a loud voice saying in heaven, Now is come salvation, and strength, and the kingdom of our God, and the power of his Christ: for the accuser of our brethren is cast down, which accused them before our God day and night.” At that point his access to heaven will be ended, and after the Tribulation he will be bound in the abyss for one thousand years (Revelation 20:1-3) and then cast into the Lake of Fire for all eternity (Revelation 20:10).
