In Revelation 21:3-4 it says,

And I heard a loud voice from the throne, saying, “Behold, the tabernacle of God is among men, and He will dwell among them, and they shall be His people, and God Himself will be among them, 4 and He will wipe away every tear from their eyes; and there will no longer be any death; there will no longer be any mourning, or crying, or pain; the first things have passed away.”

Here in this passage, it almost seems as if this promise is just for all those future believers that will experience the new heaven and earth. But I’m sure that it holds true for all believers—all who have died in the past and will die in the future. Those believers who died hundreds of years ago, their souls immediately went to be present with the Lord, and He then, at that time, wiped away every tear from their eyes. In like manner, it will happen to us too, and to all those in our future. Likewise, all who are living and are raptured, they too will be comforted with this same promise when they see Him.

As I see it from these verses, there are two things that work to fulfill these promises of His comfort: 1) they will come to us because “the tabernacle of God” has come to us—which means God’s abode, or presence. Hence, where He is, there can be no pain or fear or death or sorrow. And 2) the promise comes to us because He make all things new (v. 5). The old is past and the new has come.

The old things is the old sinful flesh, and the old body that lives only so long and dies; and it is all the pain and sorrow that goes along with it. All these things pass away with death and in their place comes new things: a new incorruptible body; and in place of sorrow and pain we will be given joy, pleasure, and delights of every kind. Psalm 16:11 tells us,  

You will make known to me the path of life;

In Your presence is fullness of joy;

In Your right hand there are pleasures forever.

Now I’m sure someone will ask; Won’t all these pleasures get old after thousands and millions of years? Won’t we get bored of all His delights? All the same old pleasures?

Well, that might be true if they were pleasures of the sinful flesh; but not from God. Not what He gives us. All that He gives us will be new and sweet every day. All that we do for Him and what He does for us will be “new every morning” (Lam. 3:23).
