*** lp chap. 10 pp. 116-117 Does God Count You Personally Important? ***
In order to resurrect a person, God has to know everything about him. Only with this information can God bring back the same person with the same personality, so that the individual will be himself and recognize himself. This means that God must restore every detail of the person's makeup. This would include his appearance, his inherited traits, the influence that environment and experience have had on him, along with his complete memory. What interest and care this demonstrates!
Someone may say, 'That seems impossible.' But even today men can make a videotape or moving picture of a person. Then, even after he is dead, they can project it on a screen and see the actions and movements of the individual, along with healing his voice. Hundreds of details are recorded. If men can do this, cannot God, with whom "all things are possible", have a record of the thousands of details that make up a personality?
*** lp chap. 15 p. 175 The End of Sickness and Death ***
As to the resurrected ones, God will accurately "re-create" each individual with his entire life pattern, personality and memory just as it was. The one resurrected will be able to identify himself as the same person. Also, his former associates will know him by his appearance and characteristics. He can then resume life after the interruption caused by his death, possessing the same motivations, leanings and traits that he displayed beforehand.... To the person who is resurrected, the time period that he was dead would be, to him, only an instant, since death is a nonexistence.
