1 Corinthians 15:39

39.All flesh is not, etc. Here we have another comparison leading to the same conclusion, though there are some that explain it otherwise. For when he says, that under the name offlesh is comprehended the body of a man as well as of a beast, and yet the flesh in those two cases is different, he means by this that the substance indeed is the same, but there is a difference as to quality. The sum is this — that whatever diversity we see in any particular kind is a sort of prelude of the resurrection, because God clearly shows, that it is no difficult thing with him to renew our bodies by changing the present condition of things.
