No sin, no sinner, no devil!
(Thomas Brooks, "A Word in Season to Suffering Saints")
"An undefiled inheritance." 1 Peter 1:4
There are few earthly inheritances—but some defilement or other sticks close to them. Many times they are gotten by fraud, oppression, violence, injustice, etc. And as they are often wickedly gotten—so they are as often wickedly kept!
The heavenly inheritance is the only undefiled inheritance. No sin, no sinner, no devil—can enter to defile or pollute the heavenly inheritance, the incorruptible crown! The serpent got into the earthly paradise, and defiled Adam's crown—yes he robbed him of his crown! But the subtle serpent can never enter into the heavenly paradise!
"Nothing impure will ever enter it, nor will anyone who does what is shameful or deceitful, but only those whose names are written in the Lamb's book of life." Revelation 21:27
