James 1:5

If any of you lacks wisdom (to guide him through a decision or circumstance), he is to ask of (our benevolent God, who gives to everyone generously and without rebuke or blame, and it will be given him.  

Our inner dialogue may not line up with the word of God. When we tell ourselves we will never be able to do this or that we are not relying on the wisdom of God to help us. If we lack wisdom and knowledge God is more than willing to help us in any situation. We have to let go of the negative self-limiting beliefs and plug into the all-knowing God.
