Indeed. When we have bumper stickers that proudly proclaim, "Christians aren't Perfect, Just Forgiven," why should be expect holy living? If that isn't the epitome of heretical theology, then I don't know what is. When we have a major catechism that proudly proclaims that the grace of God isn't sufficient to deliver us from sin, how can we expect holy living?
And without holy living, scripture says we won't see God. Pretty scary...but it's just a matter of believing it is possible—by the indwelling presence of the Holy Spirit, guiding, directing, empowering—indeed, living it—on a moment-by-moment basis. Believe and receive!
