God leaves not His children comfortless,

"God leaves not His children comfortless, but, when the darkness of winter overshadows them, then again He sends His Messengers, the Prophets, with a renewal of the blessed spring.

The Sun of Truth appears again on the horizon of the world shining into the eyes of those who sleep, awaking them to behold the glory of a new dawn. Then again will the tree of humanity blossom and bring forth the fruit of righteousness for the healing of the nations. Because man has stopped his ears to the Voice of Truth and shut his eyes to the Sacred Light, neglecting the Law of God, for this  reason has the darkness of war and tumult, unrest and misery, desolated the earth.
I pray that you will all strive to bring each child of God into the radiance of the Sun of Truth, that the darkness may be dissipated by the penetrating rays of its glory, and the winter’s hardness and cold may be melted away by the merciful warmth of its shining."
