1 Corinthians 15

 Speaking of the Resurrection, Paul taught - 

"...and with what body do they come?

36 Thou fool, that which thou sowest is not quickened, except it die:

37 And that which thou sowest, thou sowest not that body that shall be, but bare grain, it may chance of wheat, or of some other grain:

38 But God giveth it a body as it hath pleased him, and to every seed his own body.

39 All flesh is not the same flesh: but there is one kind of flesh of men, another flesh of beasts, another of fishes, and another of birds.

40 There are also celestial bodies, and bodies terrestrial: but the glory of the celestial is one, and the glory of the terrestrial is another.

41 There is one glory of the sun, and another glory of the moon, and another glory of the stars: for one star differeth from another star in glory.

42 So also is the resurrection of the dead. It is sown in corruption; it is raised in incorruption..."  (1 Corinthians 15:35–42)

Paul teaches that even though we are resurrected to never die (blood body versus a spiritual body), there will be differences.  Joseph Fielding Smith suggested that having the means for posterity will be one.
