Doubt isn't the opposite of faith — sometimes it's part of it. These verses meet you honestly in the questions.

“...Lord, I believe; help thou mine unbelief.”
Mark 9:24 (KJV)
“If any of you lack wisdom, let him ask of God, that giveth to all men liberally, and upbraideth not; and it shall be given him. But let him ask in faith, nothing wavering.”
James 1:5-6 (KJV)“Now faith is the substance of things hoped for, the evidence of things not seen.”
Hebrews 11:1 (KJV)That father in Mark 9 says something that sounds contradictory — I believe, help my unbelief — and Jesus doesn't correct him for it. That's worth noticing. Doubt and belief can be present in the same sentence, the same prayer, the same person. You don't have to resolve every question before you're allowed to bring it to God. The honesty itself can be the prayer.
