On the Christian worldview, faith is not opposed to reason. It cooperates with reason. “Faith is trusting in what we have reason to believe is true.” (synonyms for faith = trust, confidence, reliance, God-confidence).
Put another way, “Faith is a readiness to act as if something were so” (cf. Dallas Willard). It is important to notice that this is the same faith we employ when we get on airplane or decide that forgiveness is really better than bitterness and Jesus was right about that.
A challenging aspect of this understanding is also that “what we we believe is what we actually act as if it were true.” (ouch)
Finally, it is important to recognize that faith doesn’t make anything true or false…whether airplanes are safe, forgiveness really is better than bitterness, or that Jesus rose from the grave. Sincerity doesn’t make something true or false. Faith is only as good as the object in which it is placed.
