Thematic Bible: Why the body dies

But if Christ is in you, though your bodily self is dead because of sin, your spirit is full of life because of righteousness. But if the Spirit of Him who raised up Jesus from dead is dwelling in you, He who raised up Jesus from the dead is dwelling in you, He who raised up Christ Jesus from the dead will also make your dying bodily self live by his indwelling Spirit in your lives.

But some one will ask. "How are the dead raised? and with what body are they coming?" Foolish man! The seed you sow does not come to life unless it dies. And when you sow the seed you are not sowing the body that it will become, but bare grain, of wheat perhaps, or some other grain. read more.
But God gives it what body he pleases, and to each kind of seed its own body.
