That assault from legalism is why the answer is so important in dealing with the legalism of Mormonism. It is also why Paul had such problems with the 'judaisers' who sought to burden new followers of Christ with the weight of Mosaic laws and the 'fullness of the Midrash'.
Legalism is a distraction which disheartens those freed from the wages of sin and death. The guide for life once adopted into His family ought be the Holy Spirit within, not the weight of legalism without, for we know no man but Jesus ever kept all the law.
When someone is bound up in leaglism it is a sure sign of either no new life or assault from a man-made system to empower other men not the born again.
