Adam and Eve became dissatisfied with perfection. They believed they needed to be more like God when the truth was that they were already like God. Their hunger wasn't based in reality but in perception. Jesus' disciples weren't satisfied with Jesus. They said, "Shew us the Father, and it sufficeth us" (John 14:8). If Adam and Eve and Jesus' disciples could be dissatisfied with perfection, then certainly we can be dissatisfied with our imperfection.
