Good parents refuse to leave their children at the mercy of their own folly.
Exerting every effort to prepare their children for successful living, they teach them the needful skills of self-control, respect for authority, consideration for others, and submission to God. This training involves teaching, leading, correcting. In a word, this training involves discipline. First, effective discipline is consistent, but it is next to impossible to be perfectly consistent. Personal feelings often spoil our efforts to be consistent.
