1 John 2:1-6
My little children, these things write I to you, that you sin not. And if any man sin, we have an advocate with the Father…
For my own part I have no doubt the New Testament does contain a theory, or, as I should prefer to say, a doctrine of the atonement. The work of Christ in relation to sin is not a naked fact, an impenetrable, unintelligible fact; it is, in the New Testament, a luminous, interpretable, and interpreted fact. The love of Christ, says St. Paul, constraineth us, because we thus judge; i.e., because we can and do put a certain intellectual construction upon it.
