Revelation 21:8

But the fearful, and unbelieving, and the abominable, and murderers, and whoremongers, and sorcerers, and idolaters, and all liars, shall have their part in the lake which burneth with fire and brimstone: which is the second death.

This is a hard verse, but it is an honest one. The Lord is showing John that the new creation will be beautiful not only because of what is there, but because of what will never enter it. Sin will not cross that border. Evil will not slip in through a side gate. Nothing corrupt, defiling, violent, false, or dark will ever stain that city.

And the truth is, the greatest comfort in that is not merely that certain kinds of people will not be there. The greatest comfort is that the sin nature I am so tired of will not be there either.

Because if we are honest, when we read a verse like this, we are not meant to stand at a distance and say, “Those terrible people.” We are meant to feel the weight of what sin really is and what it has done to the human heart. Apart from Christ, every ugly root is in us. Maybe not every outward act, but the seeds are there. Pride. deceit. lust. unbelief. selfishness. fear. hardness. Left to itself, the flesh is never moving upward. It is always pulling downward.

That is why heaven will be such a relief to the believer. Not only because there will be no devil there. Not only because there will be no curse there. But because the flesh in us, the thing that has fought us, embarrassed us, wearied us, and tripped us for so long, will be gone.

We feel that battle now.

There are thoughts we wish did not rise.
Reactions we wish did not flare.
Temptations we are weary of resisting.
Old tendencies that make us say, “Lord, when will I ever be rid of this?”

And the answer of Revelation 21 is, one day you will.

Not managed better.
Not merely subdued.
Gone.

That is part of what makes heaven heaven. It will be a safe place because nothing false will live there, and nothing fallen in me will survive there either. The part of me that still leans toward sin will not be carried into glory. The Lord who saved me will finish the work so completely that what He began by grace He will complete in holiness.

1 John 3:2

Beloved, now are we the sons of God, and it doth not yet appear what we shall be: but we know that, when he shall appear, we shall be like him; for we shall see him as he is.

That is not small comfort. That is one of the sweetest hopes in all of Scripture. We will be like Him. Not divine, of course, but made like Him in purity, freedom, and wholeness. No double mindedness. No secret pull toward darkness. No inward war. No shame over what still clings so stubbornly now.

I think the older a believer gets, the more precious that sounds. When you are young, you may imagine freedom mainly as freedom from trouble around you. But as you walk with the Lord longer, you begin to long just as deeply for freedom from what is still wrong within you. You grow tired of the flesh. Tired of battling it. Tired of seeing how it distorts, interrupts, and weakens what you most want to give to God.

So yes, Revelation 21:8 is a warning verse. It tells the truth about judgment. It tells the truth about sin. It tells the truth about the second death. But for the redeemed, it is also a strangely comforting verse, because it reminds us that heaven will never be contaminated by the very thing that makes earth so exhausting.

There will be no lies there.
No violence there.
No idolatry there.
No corruption there.

And there will be no sinful residue in me there.

Dear friends, that means your deepest struggle is not permanent. The battle you fight now is real, but it is not eternal. The flesh that troubles you so deeply today is not going with you into the city of God. The Lord is not merely taking you to a better place. He is making you fit for that place entirely.

What a day that will be.

To love without mixture.
To worship without distraction.
To serve without pride.
To rest without fear.
To live without sin.

Heaven will be safe because every enemy outside us will be gone, and every enemy inside us will be burned away.

And for that, every weary saint can say, even now, “Thank God.”
