Most beliefs do stand or fall alone.
For example, if you believe the world is rounded, not flat, that belief is probably connected to a series of other beliefs. You probably also have a general confidence in the findings of science, and you bring to your conclusion an implicit trust that the pictures showing the curve of the earth are not fake. Christian belief also has a context. A mature and grounded faith embraces an increasingly rich complex of interwoven beliefs. In Romans, the apostle Paul connects one's commitment to certain facts with the notion of faith.
