Thematic Bible: Why the body dies

But, if Christ is within you, then, though the body is dead as a consequence of sin, the spirit is Life as a consequence of righteousness. And, if the Spirit of him who raised Jesus from the dead lives within you, he who raised Christ Jesus from the dead will give Life even to your mortal bodies, through his Spirit living within you.

Some one, however, may ask 'How do the dead rise? and in what body will they come?' You foolish man! The seed you yourself sow does not come to life, unless it dies! And when you sow, you sow not the body that will be, but a mere grain-perhaps of wheat, or something else. read more.
God gives it the body that he pleases-to each seed its special body.
