The problem is that within the church, there's been a push back against the legalism of the recent past and now any call to moral purity or integrity or holiness is called legalism by those who want to have their cake and eat it too.
But God makes it clear that holiness is not an option for His people.
IMO, those who have such a cavalier attitude towards holiness, that they can do whatever they want and it's OK with God, aren't really saved.
Anyone who really grasps what it cost to procure our salvation would not treat it with such contempt.
Amen.
