An eyesore to the damned in hell

(Thomas Watson, "The Lord's Prayer")

"There will be weeping there, and gnashing of teeth,
 when you see Abraham, Isaac and Jacob and all the
 prophets in the kingdom of God, but you yourselves
 thrown out!" Luke 13:28

A great aggravation of the loss of heaven will be to
look upon others who have gained the kingdom. The
happiness of the godly in heaven, will be an eyesore
to the damned in hell. When the wicked shall see
those whom they hated and scorned—exalted to the
kingdom, and shine with robes of glory, and they
themselves miss the kingdom—it will be a dagger at
the heart, and make them gnash their teeth for envy!
