Again: we might well inquire—have we that desire which presses us to close communion with God, which is filled with unutterable burnings, and holds us there through the agony of an intense and soul-stirred supplication? Our hearts need much to be worked over, not only to get the evil out of them, but to get the good into them. And the foundation and inspiration to the incoming good, is strong, propelling desire. This holy and fervent flame in the soul awakens the interest of heaven, attracts the attention of God, and places at the disposal of those who exercise it, the exhaustless riches of divine grace.
