“… A man who has lost a leg in childhood will have his leg restored… . Deformities and the like will be corrected, if not immediately at the time of the uniting of the spirit and body, so soon thereafter [almost instantly] that it will make no difference… . Infants and children do not grow in the grave, but when they come forth, they will come forth with the same body and in the same size in which the body was when it was laid away. After the resurrection the body will grow until it has reached the full stature of manhood or womanhood.” (Joseph Fielding Smith, Doctrines of Salvation, 2:293-294)
“The question frequently arises as to whether a child that died in infancy will remain a child in the hereafter, and whether in the resurrection the spirit will take up the same body that it tabernacled in the flesh… . . The late President Joseph F. Smith in an editorial in the Improvement Era, June 1904, … stated, ‘The body will come forth as it is laid to rest, for there is no growth or development in the grave. As it is laid down, so will it arise, and changes to perfection will come by the law of restitution. But the spirit will continue to expand and develop, to the full stature of man.’ Parents, therefore, who have been parted from their children by death may rest assured that, if worthy through obedience to the principles of the gospel, they will not only meet their children in the spirit world, but will also recognize them and know them as they knew them in this life. Parents too, have even a greater comfort in the fact that their little ones whose lives on earth were cut short will continue to grow and develop, and receive every blessing to which their inheritance and faithfulness will entitle them.” (David O. McKay, Gospel Ideals, p. 75)
“Man is a dual being, a spirit within a mortal body. It is difficult to teach about the intangible, spiritual part. But there are ways to do it… . A personal computer made of metal, plastic, glass and a dozen other materials will hold an astonishing amount of information. All of the standard works can be stored there, and in addition, sets of encyclopedias, dictionaries, books on a whole library of subjects, even illustrations and mathematical formulas. With the press of a few keys one can select any part of what is stored and see it instantly on a screen. One may, by pressing a few more keys, rearrange, add to, or subtract from what is stored in the computer. Press another key or two and you can print a copy of whatever you desire, even in full color. You then can hold in your hand tangible, absolute proof of what is inside there and how it is arranged. However, if you should take the computer completely apart, you could not find one word of it, not one illustration, not one tangible evidence that there are volumes, verses, poems, and illustrations inside the computer. You could dissolve the computer with acids or burn it and you would not find one tangible word of evidence. You could no more find words in the ashes of a computer than you can find the spirit in the ashes of a cremated human body. No one doubts that this great base of information is actually stored in the computer. It should not be too difficult to teach each youngster that there is within the human body a spirit.” (Boyd K. Packer, CES Symposium, Aug. 10, 1993)
