Will the gates of pearl be opened to let in dogs and swine?

(Thomas Boston, "Human Nature in its Fourfold State")

There is no Heaven without holiness; for "without holiness no man shall see the Lord," Hebrews 12:14. Will the gates of pearl be opened to let in dogs and swine? No! their place is outside, "Outside are the dogs, the sorcerers, the sexually immoral, the murderers, the idolaters, and everyone who loves and practices lying." Revelation 22:15. Will God take the children of the devil, and permit them to sit with Him in His throne? Or, will He bring the unclean into the city, whose street is pure gold?

Be not deceived; grace and glory are but two links of one chain which God has joined, which no man shall put asunder. None are transplanted into the paradise of glory above — but out of the nursery of grace below. If you are unholy while in this world, you will be forever miserable in the world to come!

"He who is unjust, let him be unjust still; he who is filthy, let him be filthy still!" Revelation 22:11

"C
ast the unprofitable servant into the outer darkness, where there will be weeping and gnashing of teeth!"
Matthew 25:30
