Mark 9:24
(NIV)“Immediately the boy's father exclaimed, 'I do believe; help me overcome my unbelief!'”
Context
A desperate father telling Jesus the most honest thing, 'I believe AND I don't.' Jesus heals his son anyway. The faith bar isn't certainty; it's honesty.
For your life
If your prayer right now is 'I think I believe but also I don't', that's a real prayer. It's literally in the Bible.
