The radical fringe makes the vast majority of intemperate sinners look normal by comparison. The socially conscious majority are pragmatic enough to exercise sufficient self-restraint so as to maximize their indulgence without diminishing their mental pleasure in regard to their pride of life. In other words, the middle of the road sinner will learn to balance intemperance over against his desire to appear moral. His relative self-control is prompted by desires to both indulge and maintain a reputation that offers the most mental satisfaction. If you learn to function this way without hurting anyone other than a few people close to you, society will consider you mature and emotionally stable.
Sin has many roots and quite a few disguises.
In our present age, a child has no hope unless his parents have the wisdom and courage to ignore modern psychology and the low expectations of the church as they train up the child in the way he should go. It is the parent's responsibility to cause the child to exercise moderation and restraint. When a child is less than two years old, you cannot expect him to offer any assistance in constraining his appetites and drives. He will eat everything that tastes good, demand anything that appeals to him, expect to be the center of attention, and is unwilling to wait for any reason. For the constraint to translate into soul training it must make use of the child's will.
