Far from being a Savior, the god of Unchristianity is a coach who whips us into moral shape, inspires us to be better people, serves as our example. The unspoken goal is to be so virtuous and free of sin that we don’t need Jesus anymore. The transaction is complete. Jesus is unemployed.
If God ever forgives you, it is not just allowing you to start over and try harder the second time, but it is a whole, new, complete justification that is given as a free gift and without any work of our own—outside the law.
