Note, 1. To the education of children in that which is good there is necessary a due correction of them for what is amiss; every child of ours is a child of Adam, and therefore has that foolishness bound up in its heart which calls for rebuke, more or less, the rod and reproof which give wisdom. Observe, It is his rod that must be used, the rod of a parent, directed by wisdom and love, and designed for good, not the rod of a servant. 2. It is good to begin betimes with the necessary restraints of children from that which is evil, before vicious habits are confirmed. The branch is easily bent when it is tender. 3. Those really hate their children, though they pretend to be fond of them, that do not keep them under a strict discipline, and by all proper methods, severe ones when gentle ones will not serve, make them sensible of their faults and afraid of offending. They abandon them to their worst enemy, to the most dangerous disease, and therefore hate them. Let this reconcile children to the correction their good parents give them; it is from love, and for their good, Heb 12:7-9.
