In eternity, we shall rather be in a state better than that of Adam in the Paradise.. Adam and Eve were in a state of righteousness but liable to fall.. but in eternity we shall have the crown of righteousness, which righteousness is not subject to falling..
If we shall be in a better state than that of the first man before the fall. Then, at least, we shall be like him in innocence, purity, simplicity and knowing no sin..
