Because we each have a physical body, we already have the single best reference point for envisioning a new body. It’s like the new upgrade of my word processing software. When I heard there was an upgrade available, I didn’t say, “I have no idea what it will be like.” I knew that for the most part it would be like the old program, only better. Sure, it has some new features that I didn’t expect, and I’m glad for them. But I certainly recognize it as the same program I’ve used for a decade.
Likewise, when we receive our resurrected bodies, we’ll no doubt have some welcome surprises—maybe even some new features (though no glitches or programming errors)—but we’ll certainly recognize our new bodies as being ours. God has given us working models to guide our imagination about what our new bodies will be like on the New Earth.
