How can someone confidently believe that God exists, but also have moments of serious doubt about whether the belief is true? A religiously significant belief that God exists is a by-product of adopting a perceptual framing narrative which presupposes God's existence. Using such a narrative is a type of skilled performance that results in an awareness of theistic significance which may at times be disrupted. At such times, doubts may arise about theistic meanings, which can exist in tension with confidence derived from using the theistic narrative as a practical guide. The relevant reflective question for believers with serious doubts is whether some alternative framing narrative is more believable and also capable of engaging them in a way of life.
