Mark 9:23 - Possibilities

“And Jesus said to him, “ ‘If You can?’ All things are possible to him who believes.””
‭‭Mark‬ ‭9‬:‭23‬

It seems to me that belief (or faith) is what you understand to be true. It takes both, understanding and truth. You don’t need 100% understanding or 100% knowledge of truth to believe something. But, if you don’t understand something or don’t think it is true, you cannot believe it. To help, or grow your belief (or faith) it requires you increase your understanding or the truth. Nowhere in Scripture will you find an example of blind faith or nonsense. It is logical, reasonable and evidence based decisions that lead a person to belief (of faith) in the God of the Bible. The gift of the Holy Spirit is what gives us the ability to understand it to be true.
