Fences are not enough

As parents, we are sometimes more interested in protecting our children from the sinful influences of the world than we are preparing them for the deep sinfulness of their own hearts. We think that if we can just keep them from sinning too much while they are young and vulnerable, then they won't struggle with sin so much as adults. Of course, good parents don't allow their kids to sin much. They discipline, teach, restrain, and intervene. Yet these actions alone don't prepare young people well for the reality of the powerful temptations they will face when Mom and Dad aren't around. Simply building a fence between a child and temptation is not the same thing as preparing him to face life.
