I tend to struggle with the idea of mans sanctification. I tend to disagree a bit with the reformers on it. For one the idea of faith without works I am vehemently for.
On the other side if the coin I can become arminian and believe man needs to cooperate synergistically with God as much as his sinful nature will allow. Is it the cooperative synergism with God that sanctifies me? I dont know but I dont loudly proclaims against this synergism either like some do in the religious ranks just to hang on to a theological point.
No matter how my sanctification works I know I have Jesus, the author and perfecter of my faith. Because of what Jesus did I have assurance that He will see me through and not because of anything I can do.
In my own personal walk I have seen sanctification come through my understanding of my wife. She is radically different from me. As I “work” to understand this love despite these radical differences and as we both collectively and continuously embrace the Gospel I believe I see growth.
Hopefully its Gods sanctified work through Jesus Christ being reflected in me …. I dont know… but it feels good.
