God does not need us to “make good” to him in order for him forgive us. However, humans may need us to do so. There is such a thing as manifesting (bringing forth) fruit of repentance. This makes hyper-Protestants nervous. It need not be so.
Here, Crosby makes the point I’ve been approaching by asserting that the sin God deals with on the Cross is our sin against Him, not our sign against others.
