As noted in the opening post in this series, I believe Christianity offers compelling reasons to believe that truth is found most fully and consistently within the framework of a Christian worldview. The second post addressed the need for an objective foundation for morality. The language of morality only makes sense if we are significant moral agents who have an obligation to choose good and avoid evil, so the third post addressed the issue of whether or not we are really free.
The concepts of freedom and moral obligation brings with them the idea of justice. If right and wrong are objectively real, and we are people deserving of praise and culpability based on how our choices align with moral goodness, then part of the morally obligatory good would be to treat people justly. So, what is justice?
