Thematic Bible: Why the body dies

And if Christ is in you, the body is dead because of sin, but the Spirit is life because of righteousness. But if the Spirit of him who made Jesus come again from the dead is in you, he who made Christ Jesus come again from the dead will in the same way, through his Spirit which is in you, give life to your bodies which now are under the power of death.

But someone will say, How do the dead come back? and with what sort of body do they come? 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; read more.
But God gives it a body, as it is pleasing to him, and to every seed its special body.
