On the contrary, we believe it was SO good that it enables us to contribute to healing the wounds we've inflicted on our selves and others. It was SO good that we can participate not only in being saved but in saving. It was far better than anyone would dare dream.
What utter nonsense. If Jesus sacrifice was a perfect and complete sacrifice for all our sins it is denying that by implying that we can do anything to “assist” or “participate” in any way. And you don’t “participate” in saving.
