Each of these authorities sees an external aspect to holiness. Unfortunately, few Christians I know place the same priority on this half of the Hebrews' injunction as on the first. While many agree that the church's goal should be to see that no one is sexually immoral , they don't see how that is any of their business. These issues are not considered part of being holy. They are external.
Personal holiness is personal, after all.
It's concerned with me, not with the welfare of those around me. In large part, we are a people of faith who have bought into the propaganda of the ungodly world, compromised our own truths in order to live in peace with the heathen, and even accepted the agenda of relativism that has characterized our culture for decades. Statistics today show that the same percentages of Christians participate in immoral practices and behaviors as do nonbelievers. In order to live in peace with all men , we have not held ourselves to be holy , we have not been critical of immorality in our midst and we have allowed many to be godless without any protest. Instead, we have focused inwardly with unrighteous tolerance of the external and said the rest of the world is not our concern.
