Without a sense of the shame or guilt of his or her action, the child will only be hardened in rebellion by physical punishment. Shame (and praise) help the child to internalize the parent's judgment. It impresses upon the child that the parent is not only more powerful but also right. Like the Puritans, Locke (in 1690), wanted the child to adopt the parent's moral position, rather than simply bow to superior strength or social pressure.
Prayer that works is prayer that makes a difference, contemplation that turns into action, on behalf of peace and justice in a troubled and unjust world system. Prayer is energy, the energy of love and transformative power. It is given to us to use for the good of all creation. In prayer God gives us the fuel of life, and asks us to live it.
