Why do people radicalize their assumptions about Jesus, the Bible, and related matters? That is, they adopt extreme, unnecessary, and unwarranted presuppositions regarding these things. For example, they start off with an assumption about the resurrection of Jesus being improbable but somewhere along the way make the slight but profound shift from thinking of it as improbable to thinking of it as impossible. Thus they take a reasonable assumption (resurrection would be very extraordinary) and make it radical (such a thing never could happen).
I have to think that some people radicalize their assumptions because they are afraid of where an open mind might lead them.
Some people don’t want to believe that Jesus Christ was raised from the dead because they fear what such a reality would do to their lifestyle. Therefore, they shut off all objective inquiry by radicalizing their assumptions to preclude ever reaching that conclusion.
Therefore, radicalized assumptions have a very practical purpose for those who do not wish to answer even to God for what they do with their lives. However, sooner or later we shall all answer to God for what we have done with our lives. The sooner we embrace His authority, the happier we will be when we give the answer.
Do not close and lock your mind with radicalized assumptions. It leads only to counterproductive outcomes.
