A Course in Miracles says:

⁴The Oneness of the Creator and the creation is your wholeness, your sanity, and your limitless power. this limitless power is God’s gift to you because it is what you are.⁶ If you dissociate your mind from it you are perceiving the most powerful force in the universe as it if were weak, because you do not believe you are a part of it.

ACIM M7.VI.3.10:4-6

This stuff is hard to understand without the context. I guess most of the time it’s even hard to understand with the context.
