Americans are addicted to almost anything now days. Americans are addicted to food and the obesity rate just seems to be skyrocketing. They are obsessed with their social image. Forty-eight percent of Americans have some sort of social account and they check it constantly. This has also lead to an addiction to technology. The rise of smart phones is making it easier to access the internet no matter where a person is. Americans are addicted to coffee. To a normal America, you cannot get enough caffeine. Americans are also obsessed with crime shows. They are addicted to illicit sex and immorality runs rampant. Because of such behaviors abortion is at an all time high. There are those addicted to drugs, pain killers, gambling, and the list goes on. In short, Americans are addicted to almost any thing and simply put: American have little if any self-control. The reason why people struggle with addictions is because they cannot control their appetites. So what is the cure for such addictions and how can someone gain more self-control? The answer is Religion.
It can be said that self-control is the master virtue. With it one can obtain all the other virtues. In their book Handbook of the Psychology of Religion and Spirituality, Poloutzian and Park discuss three main elements of self-control. The first element is there needs to be an ultimate standard. Each person needs to know what to do. Secondly, each person needs to monitor his own behavior. The individual needs to know how he is doing in relation to the standard. And thirdly, the person needs to have the will power and the ability to change to that standard (pg. 414-415). Now there have been many papers done exploring the effect of the religion on the human psyche to help and individual gain self-control (see McCullough and Willoughby2009). There have even been studies done on people to see if these papers are true (see Rounding et. al. 1012). They have found that religion does help someone gain self-control. Why is this? Poloutzian and Park speak about this also. First off, religion gives a standard for one to follow after. Secondly, it provides motivation. Every religion gives plenty of reason why the striving for the ultimate standard is good- the most basic is G(g)od wants him to. Third, religions have times and ways for people to monitor their growth in self-control. Fourth and maybe the most important one, is religion can help a person monitor his desire for vices (418-425). So by this religion can help one curb their desire for vices and give them self-control; however, this will not help an individual in the long wrong. It will merely curb their appetites. Ultimately the issue is a heart motive that needs to change.
Christians view evil as being a deprivation of the good. Augustine said that evil is a provatio boni. This means evil does not possess its own essence. It is merely the privation of good; similar to the color black. Black is not a real color but the absence of color, so evil is the absence of good. However, Augustine expands on this idea in Confessions. In it he says evil can also be the abuse of evil. Taking this view, everything is good in and of itself, but becomes evil when it is abused. What man seeks for is joy. He tries to find it in all the temporal pleasures around him and by doing so he abuses them and turns them into vices. Kiekegaard believed every soul longed for God but most men tried to fill this longing in other worldly things (Four Upbuilding Discourses). Likewise, Augustine said, "Almighty God, you have made us for yourself, and our hearts are restless till they find their rest in you" (Confessions book 1 chapter 1). So true joy and happiness is found in God and what he has done for us through Christ on the cross. We do not need to seek joy in other things outside of Christ, but it is who and what Christ has done for us that satisfies man. And it is only until a person realizes this can he truly have self-control. For without the ultimate form of joy in their life, they will seek out joy in other things. So while religion in general can give a form of self-control, it is only Christianity that can give true joy that leads to everlasting contentment which will produce ultimate self-control. The heart will have what it longs for- Christ- and it will not longer have to seek it out in temporal objects.
