Ezekiel 18:4 “Behold, all souls are Mine; the soul of the father as well as the soul of the son is Mine. The soul who sins will die.”
In this series of posts, we are considering the relationship between sin and moral character (and more specifically, moral agency, in general).
The first thing that must be said is, if we eliminate moral agency, intentionally or inadvertently, we also eliminate sin (and we eliminate righteousness). The reason for this is that sin requires moral agency. To say it in a ridiculous way, a rock cannot sin. We can even say, a dog cannot sin. Why? Neither the rock nor the dog possess moral agency and therefore, cannot sin nor can they produce moral character. This is a point of importance as we evaluate certain popular and influential theories that have surfaced in the Christian community. One such theory, to be considered in our next post, is the doctrine of inability.
 It is important to explain the significance of this statement as we live in an age in which most people are not familiar with the language and concepts being employed. The possession of moral agency means that human beings have the capability to choose between opposing options; proper and improper options (this implies a “standing,” moral law). If the capability to choose between options does not exist, then sin is not an option and is thereby a meaningless concept (this also applies to righteousness as both are moral concepts). I hear considerable language used by Christians that eliminates moral agency and, thereby, eliminates moral concepts such as sin and righteousness, virtue and vice.
