My wife and I were discussing this the other day: "What will we look like in Heaven? Will we be the last form of our bodies on earth or the prettiest or what?" I haven't looked up the verses I remember about yet, but I remember them being interpreted as we will have some spiritual form, maybe like light. But we won't have our earthly bodies, because they return to dust, and why would looks matter in Heaven anyway? We will still recognize people we have known based on their inward appearances instead of outward, because it will be all spiritual and not physical like earth. At least that's what I remember learning a while back. Any other more recent, cogent Biblically-sound answers?
