The Bible is full of people who doubted and were not abandoned for it. Abraham laughed when God told him he'd have a son at ninety years old. Gideon asked for a sign β twice, with a fleece. John the Baptist, in prison, sent messengers to ask Jesus: "Art thou he that should come, or do we look for another?" Jesus answered with evidence, not rebuke. Doubt, when it drives you toward God rather than away from him, is a form of faith in motion.
Charismatic theology takes doubt seriously because it takes experience seriously. When your experience contradicts what you believe, the tension is real. The answer is not to deny the experience or pretend the confusion doesn't exist. The answer is to bring the confusion honestly into God's presence, where the Holy Spirit can meet it.
James does warn against wavering in prayer β but the word he uses (diakrino) specifically describes divided loyalty, not honest intellectual struggle. Asking God hard questions is not the same as refusing to commit. The person who prays "Lord, I believe; help thou mine unbelief" is not double-minded. They are being honest about where they are.
