Teach them to Love. Start this at the very beginning.
Teach them faith -- fearless, unshakeable confidence.
Teach them humility -- complete selflessness, giving to others and thinking not of themselves.
Teach them responsibility -- perfect, 100% responsibility for everything that happens to them. With this, they can never blame (and blame is incompatible with love, faith and humility).
Teach them gratitude. If they are grateful, all karmic debts are paid and they move even closer to God.
By these, your children will be following Christ.
