“Creation’s freedom promises my own.”
How could the expression of something that is free in nature not be free? Only when it thinks of itself as bound or limited. This illustrates the pivotal element in all of this: your thinking and thought processes.
Thoughts that are not being guided by Source’s core qualities will lead you astray and will make you feel constrained. However, thoughts that are being guided and directed by Love in any of its aspects, will lead you to the experience of Blessedness, Unity and, yes, Freedom.
