At death, the Christian gains holiness without sin. In Heaven, the very existence of sin will be destroyed, "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
Here on earth, sin is the ruin of man--the ruin of his immortal soul. It has blighted and blasted the world, and filled it with impurity, misery, and death!
The Christian has here to struggle and wrestle . . .
with sin in his members,
with his depraved heart,
with sin in his family,
with sin in his neighbors,
with sin in his business transactions,
with sin in society at large.
He feels its evil operations, and laments its corrupting effects.
But in Heaven the Christian shall gain purity without sin! All the remains of sin, and the dregs of corruption are left forever behind!
No condemning conscience is found there.
No unhallowed appetites are found there.
No disordered affections exist there.
No appearance or vestige of evil is found there.
Every child of God is as pure as Christ is pure--as perfect as his Father in Heaven is perfect.
Child of mortality, heir of corruption! Look forward to your sinless and perfect home, and learn that to die will be gain indeed!
"Now the dwelling of God is with men, and He will live with them. They will be His people, and God Himself will be with them and be their God. He will wipe every tear from their eyes. There will be no more death or mourning or crying or pain, for the old order of things has passed away!" Revelation 21:3-4
