Shaky: When Doubt Comes from a Misunderstanding of Belief

Doubt can come from many sources. Some people doubt Christianity because their beliefs are not based on knowledge to begin with. They have a fundamental misunderstanding of what Christianity really is. Others doubt or reject Christianity because they have trouble dealing with what it would really mean for their lives if it is true. They don’t want it to be true.

Some people, however, doubt Christianity when their understanding of belief itself breaks down. People embrace one of what my friend Mark Mittelberg describes as different “faith paths.” There are six such paths:

  • The “relativistic faith path” says that truth is what you make it.
  • The “traditional faith path” says that truth is what you’ve always been taught.
  • The “authoritarian faith path” says that truth is what you’ve been told to believe.
  • The “intuitive faith path” says that truth is what you feel in your heart.
  • The “mystical faith path” says that truth is what you think God told you personally.
  • The “evidential faith path” says that truth is what logic and evidence point to. 1

Of these six, Mittelberg says, only the last one accurately represents the biblical idea of a believing faith. His intent in focusing on logic and evidence is not to diminish the work of the Holy Spirit in securing salvation (Eph. 1:13) but rather to point out that other paths have the most potential for distorting belief by making it a matter of personal preference, tradition, or feeling. People who walk along one of the other faith paths are more likely to question Christianity’s uniqueness to the point of changing their convictions.

If you find yourself objecting to the idea that only one of these paths is legitimate, you’re not alone. Most people think of faith as believing in something without good reasons.2 However, this ought not to be the case.

The Bible does not discourage knowing things as a foundation of belief. In fact, it encourages it. Isaiah 43:10–11 says, “‘You are my witnesses,’ declares the LORD, ‘and my servant whom I have chosen, that you may know and believe me and understand that I am he. Before me no god was formed, nor shall there be any after me. I, I am the LORD, and besides me there is no savior.’” John 20:30–31 says, “Jesus did many other signs in the presence of the disciples, which are not written in this book; but these are written so that you may believe that Jesus is the Christ, the Son of God, and that by believing you may have life in his name.” Clearly the Bible itself encourages us to believe based on the presence of knowledge and evidence rather than its absence.

Christian faith, therefore, is not opposed to knowledge; rather, it consists of acting—indeed, trusting—in accordance with what we know.
