"Our first problem (with holiness) is that our attitude toward sin is more self-centered than God-centered. We are more concerned about our own 'victory' over sin than we are about the fact that our sins grieve the heart of God. We cannot tolerate failure in our struggle with sin chiefly because we are success-oriented, not because we know it is offensive to God."
Now, I know that weight loss and dieting is not always equivalent to holiness. But I also know that my personal failure to exercise self-discipline in the areas of healthy habits is a result of failing to appropriate God's grace and power by an deliberate act of faith. And whatever is not of faith IS sin....And sin IS "offensive to God", as Bridges states.
As I continue the journey of a healthy lifestyle, I want to keep my eyes on the fact that failure in this area is not so much about me - my failure or success - but is about the heart of God - His glory, His holiness, His power, and His love for me, His child!
