I reject (because it is untrue) that double-negative understanding of the work of Christ which is expressed in terms of his saving us from a punishment that God imposed.
The work of Christ should be understood in terms of what he positively did for us: what he enabled, and taught, and demonstrated.
Jesus made it possible for us to be free, as well as Good - recognising that values based upon passive, unconscious obedience to external authority (of any kind, even when that authority is truly divine) are insufficient.
To be ours, to count to our credit, to be worthy of full sons and daughters of God; values must come from-within - that is from our selves - and from our real, true, divine, eternal selves; and be freely chosen.
Christ both made this possible by a cosmic effect - by which his incarnation, death and resurrection changed the universe - and also by his life-as-teaching he showed us how this works in practice.
Jesus was the first and only complete 'primary thinker' - whose thinking was of reality, was fully participating in creation and was intrinsically creative.
Jesus did not passively follow external rules or laws (which can never be more than approximately or averagely right, which match only imperfectly with experience) - but acted directly from his divine nature; knowing the specifics of each situation and doing the one-thing-needful.
This is why the responses and actions of Jesus could never be predicted; yet always were perfect, unique and correct (but we recognise this only after they have happened).
Thus we can understand the work of Jesus in terms of allowing and implementing (gradually, incrementally, at first very imperfectly - and far from completed) the development of real Freedom - which is the agency of the real self.
Which is eventually to know and freely-choose Good in the way of divinity - which is to say to be Good consciously (in full self-awareness), actively and from-our-selves.
