Therefore, if anyone is in Christ, he is a new creation; the old has gone, the new has come.
2 Corinthians 5:17
Upon their creation, God declared Adam and Eve to be “very good”; actually made in his divine image. And once God pronounced his creation to be “very good” in the beginning, then, regardless of what happens between times to defile it, his handiwork (all of it) must still be no less than “very good” in the end. He cannot (and will not) permit his original good work to be permanently damaged, diminished or ultimately destroyed (see Rev 21:4-5).
That said, it would seem that Adam and Eve must have sinned very soon after their creation. Some important sixteenth and seventeenth century scholars calculate the fall of the first couple as early as the second day after the creation events. The scriptures teach that God was very busy through the creation process. Nonetheless, on the seventh day he rested (Heb: shabat = “ceased”) from all his work” (Gen 2:2). What is not recorded, however, is that God went ‘back to work’ on the eighth day; the work of renewing everything that had been ruined by Adam’s fall. Jesus would later allude to this when he said, “My Father is always at his work to this very day, and I, too, am working” (]n 5:17).
