Do not think you can know the will of God apart from a willingness to do it.  A surrender to the will of the Father becomes a way of knowing.  To become a living sacrifice is the path to discerning the mind of God.  Full consecration may end your confusion and uncertainty.  A mind conformed to the ways of the world is not even on the same channel as finding the mind of God. To love God with your whole being and to want His way above your way is the path to knowing.

“I appeal to you therefore, brothers and sisters, by the mercies of God, to present your bodies as a living sacrifice, holy and acceptable to God, which is your spiritual worship. Do not be conformed to this world, but be transformed by the renewing of your minds, so that you may discern what is the will of God—what is good and acceptable and perfect.” Romans 12:1–2 (NRSV)
