An excerpt from a book entitled The Journey, Our Quest for Faith and Meaning, written by Karen Lee-Thorp:
Belief in something doesn’t make it true; only truth makes a belief true. But without truth, a belief may only be a sincere speculation. True beliefs then, are beliefs that correspond with reality. When the Christian faith claims to be objectively true, that declaration directly opposes those that are typically modern.
Thus, Christian faith is not a form of relativism- true only “for us”.
Being objectively true, it is true in a way that is independent of majority decisions and cultural perspectives.
Nor is Christian faith subjectivism- true only because “we feel it.”
Feelings come and go, and thus are unreliable ground for faith; truth is needed to ground feelings.
Nor is Christian faith pragmatism-true simply “because it works.”
Rather, it works because it is true.
In sum, the Christian claim to objective truth means that truth is true even if nobody believes it; falsehood is false even if everybody believes it.
