Romans 8:23

Romans 8:23. And not only they, but ourselves also, which have the first fruits of the Spirit, even we ourselves groan within ourselves, waiting for the adoption, to wit, the redemption of our body.

As yet the body is under bondage. The body is dead because of sin: hence those headaches - this palpitation of the heart - this heaviness of the day which incases us: but by-and-bye, as the material world is to be delivered from its bondage, so shall these bodies also pass away from all the encumbrance of weakness, and disease, and death, into a better state.
