Where God is given will, he produces that readiness to obey. In other words, when we eventually make a determined choice to stop demanding our own way, God begins to reproduce within us his strength of character that redefines our choices. Most of the time, this is exactly what keeps us in the compromising circle anyway - choices that need a little redefinition! His character reproduced within us isn't going to just come alongside impure character within us - it replaces it!
Think of God's grace as "stem cells" that have the ability to reproduce "good" and "vital" cells of solid character within. They are the "cells" that will overcome the "bad cells" of our own character that need to be gone anyway! We might "want to" change our character - but we lack the right "cellular materials" I would like to call the "purity cells". The character of God is exactly that - so he takes his "purity cells" and transplants them through "grace moments".
The thing that makes the difference when that "transplant" occurs is our openness to receiving the new "cells" of his character. If we are really desirous to have a change of character, we usually don't "reject" that new growth - but we embrace it. Yes, there will be a conflict because nothing within us dies easily when it comes to our sin nature, but it is possible the more we focus on doing the right stuff that allows those "purity cells" to take hold! Just sayin!
