Thematic Bible: Why the body dies

But if Christ [is] in you, the body [is] dead because of sin, but the Spirit [is] life because of righteousness. And if the Spirit of the one who raised Jesus from the dead lives in you, the one who raised Christ Jesus from the dead will also make alive your mortal bodies through his Spirit who lives in you.

But someone will say, "How are the dead raised? And with what sort of body do they come?" Foolish person! What you sow does not come to life unless it dies. And what you sow [is] not the body which it will become, but you sow the bare seed, whether perhaps of wheat or of some of the rest. read more.
But God gives to it a body just as he wishes, and to each one of the seeds its own body.
