The most successful parents are those who not only teach their children, but also teach their children to teach their children to teach their children the way of the Lord. Doing this, we can place our trust in "the faithful God who keeps covenant and mercy for a thousand generations of those who love Him and keep His commandments." (Deuteronomy 7:9).
"Nevertheless, when the Son of Man comes, will He really find faith on the earth?" (Luke 18:8). Much depends upon the manner in which we teach others to "shine as lights in the world, holding forth the word of life" (Philippians 2:15-16).
