Thematic Bible: Why the body dies

But if Christ is in you, though your body must die because of sin, yet your spirit has Life because of righteousness. And if the Spirit of Him who raised up Jesus from the dead is dwelling in you, He who raised up Christ from the dead will give Life also to your mortal bodies because of His Spirit who dwells in you.

But some one will say, "How can the dead rise? And with what kind of body do they come back?" Foolish man! the seed you yourself sow has no life given to it unless it first dies; and as for what you sow, it is not the plant which is to be that you are sowing, but a bare grain, of wheat (it may be) read more.
and to each kind of seed a body of its own.
