Commenting on Romans 5:9-11, John Stott writes in part
If, therefore, we are asked by some brash evangelist whether we have been saved, it would be just as biblical to say 'No' as to say 'Yes', although the correct answer would be 'Yes and No.' For yes, we have been saved through Christ from the guilt of our sins and from the judgment of God upon them, but no, we have not yet been delivered from indwelling sin or been given new bodies in the new world.
This explains a lot about a Christian's present situation. With the rest of creation, we all do groan so from time to time, as we do also celebrate.
