The Christian Teaching was illumined by the Divine Sun of Truth, therefore its followers were taught to love all men as brothers to fear nothing, not even death! To love their neighbours as themselves, and to forget their own selfish interests in striving for the greater good of humanity. The grand aim of the religion of Christ was to draw the hearts of all men nearer to God's effulgent Truth.
If the followers of the Lord Christ had continued to follow out these principles with steadfast faithfulness, there would have been no need for a renewal of the Christian Message, no necessity for a re-awakening of His people, for a great and glorious civilization would now be ruling the world and the Kingdom of Heaven would have come on earth.
But instead of this, what has taken place! Men turned away their faces from following the divinely illuminated precepts of their Master, and winter fell upon the hearts of men. For, as the body of man depends for life upon the rays of the sun, so cannot the celestial virtues grow in the soul without the radiance of the Sun of Truth.
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. (‘Abdu'l-Baha, Paris Talks, pp. 32-33)
