Human Nature and Sin

I'm taking a class on Christian Ethics that has introduced me to the theology of Reinhold Niebuhr. He wrote about the origin of sin in such a way that illuminates the psychological concepts inherent in our faith. One could conceptualize his theology of sin with two equations:

Freedom + Finitude = Anxiety
Anxiety + Disbelief = Fear

Freedom lies in our free will. We have the power to choose right and wrong. But we are also finite human beings. We are limited by our life experiences and by our nature. The combination of our freedom and limits creates anxiety. We become aware that we are not self-sufficient and that leads to worrying that we will not be satisfied. This is part of how God created us and, in itself, is not sin. The anxiety that Neibuhr speaks about is a precursor for sin but is also the precursor for true faith.

Our reaction to this anxiety is what is important. If we choose not to place faith in God, but to live in disbelief, then we will end up with fear. Humans deal with fear in two main ways: pride and abdication of responsibility. We will accumulate wealth and power to maintain the illusion that we are self-sufficient. This requires self-deception. We need to lie to ourselves in order to believe that we can take care of ourselves.

But there is another sinful solution to the fear we experience. We can pretend we are not responsible for our actions. We become resentful of others or we engage in sensuality. At no point do we claim agency of our actions. Instead, we blame, repress, or rebel.

Psychologically, acceptance of our reality is the solution to this problem. But that leaves us at the point where we can easily despair. Facing the reality that we cannot satisfy our selves can be scary. From this perspective we see the advantage of faith in God that allows us to trust God to satisfy our spiritual needs. By consciously surrendering our freedom to God, we can accept our limitations. Instead of inspiring dread, we gain serenity from our limitations because that only increases where God will work. As Paul wrote, "To keep me from becoming conceited because of these surpassingly great revelations, there was given me a thorn in my flesh, a messenger of Satan, to torment me. Three times I pleaded with the Lord to take it away from me. But he said to me, 'My grace is sufficient for you, for my power is made perfect in weakness.' Therefore I will boast all the more gladly about my weaknesses, so that Christ's power may rest on me." (2 Corinthians 12:7-10)
