Challenges to Faith

One of the most seductive arguments against faith in God is the idea that faith is optional. This argument is usually offered by people who refuse to accept any ethical obligations. This argument is insidious because it is normally preceded by excuses for why God does not exist or the church is unattractive or just plain obstinance. What matters is not the excuse given but rather the motivation—laziness, self-centeredness, and the like. The Apostle Paul had little time for such people and simply advised the Thessalonian church: “If anyone is not willing to work, let him not eat.” (2 Thess 3:10) However, since few people accept Paul’s admonition today without qualms, let us examine the arguments.

The first inference, that faith is optional, ignores the problem of idolatry and is simply counter-factual, from a scientific perspective. Let me turn issue to each issue in turn. Then, let me address the usual excuses.

If we treat faith as optional, we frequently fall into idolatry. The problem of idolatry today has less to do with worshiping statues of pagan gods than with misplaced priorities. We commit idolatry whenever we place anything other than God as the number one priority in our lives and it is a sin because it breaks the First Commandment given to Moses: “You shall have no other gods before me.” (Exod 20:3). The sin of idolatry is often taken lightly, but this a mistake because idolatry is life threatening.

To see the threat posed by idolatry, consider what happens when alternatives to God become our number one priority. Common today, for example, is to place work as the number one priority in our life. What happens then when we lose our job or our ability to work? Americans, particularly men, are prone to depression and suicide when a job is lost and cannot be replaced for whatever reason.[1] People who cannot work, like the mentally disabled, the young, the old, the uneducated, are treated badly. When we neglect our faith in God, we end up committing idolatry, which threatens our self-esteem and our relationship with people we should care for.

If we treat faith as optional, we also fail to understand how faith undergirds modern science. Knowledge based on the scientific method follows a distinct method for testing knowledge’s veracity. These steps are usually employed: a problem is defined, observations are taken, analysis is done, a decision rule is imposed, an action is taken, and responsibility is born (Johnson 1986, 15). The very first step in the scientific methods (problem definition) requires beginning with assumptions and a hypothesis. These assumptions are faith statements—no testing can be done without them. Faith is simply not optional.

The two most famous excuses for why many people believe that God does not exist were given by Karl Marx and Sigmund Freud (1927). Marx (1843) commented that: “Religion is the sigh of the oppressed creature, the heart of a heartless world, and the soul of soulless conditions. It is the opium of the people.” By contrast, Freud (1961, 30) characterized religion as an illusion, a kind of wish fulfillment. While both Marx and Freud can be considered authority figures, the thrust of their argument is not due to a lengthy scientific analysis, but is presented more as simple slander, acceptable primarily as an excuse for decisions reached for other reasons. If we take faith as necessary part of a rational decision process, then simple slander does not warrant further investigation because burden of proof lies with those advancing a particular argument to make their case, which in this case was not done.

As Christians in a postmodern context, we have inherited a worldview which is quite capable of interpreting the world as we know it. In fact, Western civilization is built on premises advanced from the Christian worldview. The question for those who advance criticism of that worldview, normally by picking on some of its assumptions (or disputing its ethical requirements), is not how can we accept those assumptions. Rather, because those assumptions form a coherence and ethically defensible system, the question is whether alternative assumption can be used to construct a better system.

For the most part, proposed postmodern alternatives to the Christian worldview, such as deconstructionism, refuse to accept the responsibility for benefiting everyone, preferring to focus on criticism without advancing alternative, morally-defensible systems. Others talk about rights, but not responsibilities, for their client groups. Either position is morally reprehensible leaving many people hopeless and abandoned. Yet, powerful groups have advanced such changes primarily to enrich themselves at the expense of others.

These challenges to faith are repeated daily in the media, in our schools, and in society, yet they lack merit as an alternative to faith and cause significant harm to many people through their promotion of idolatry and other sins that isolate people from God, from themselves, and even from the science that has brought humanity numerous benefits.
