1 Corinthians 15:36-38

Foolish man, it is necessary for the seed which you put into the earth to undergo death in order that it may come to life again: And when you put it into the earth, you do not put in the body which it will be, but only the seed, of grain or some other sort of plant; But God gives it a body, as it is pleasing to him, and to every seed its special body.
