senses trained to discern

I've decided that wisdom is the ability to discern the voice of God from all others. Solomon asking for wisdom was merely him asking for a clearer connection to the Almighty, one without the noise. As someone who has fought the noise all his life, wisdom seems like such an unreachable goal.

How do you discern the voice of the liar from the voice of yourself, especially when your doubts mirror the liar's doubts? And trying to doublethink makes it even harder, since if you're supposed to go against the liar's voice, is ignoring your doubts actually wisdom?

How do you discern the voice of the One from the voice of yourself, especially when your desires mirror the One's desires? And trying to doublethink makes it even harder, since if you're supposed to ignore your desires, is giving in actually wisdom?
