By Elder Paisios the Athonite
Parents have to help their children spiritually when they are little; because then, even their faults are little and they can easily be corrected. It's like a fresh potato; if you scratch it a little, it's peeled. If, however, it gets older and staler, you will need a sharp knife to clean it; and if it has some dark spots, you'll need to dig deeper. If the children are filled with Christ from an early age, they will always remain close to Him. And even if they should stray a little when they grow up, either because of a phase of rebellion they're going through or because of bad influences, they are sure to return to their senses. This is because the fear of God and the devotion that watered their hearts - when they were young - cannot ever be eradicated.
