The answer from God’s word:
“… without the guidance of God, no matter how much rulers and sociologists wrack their brains to preserve human civilization, it is to no avail. No one can fill the emptiness in man’s heart, for no one can be the life of man, and no social theory can free man from the emptiness with which he is afflicted. Science, knowledge, freedom, democracy, leisure, comfort, these are but a temporary respite. Even with these things, man will inevitably sin and bemoan the injustices of society. These things cannot allay man’s craving and desire to explore. Because man was made by God and the senseless sacrifices and explorations of man can only lead to more distress. Man will exist in a constant state of fear, will not know how to face the future of mankind, or how to face the path that lies ahead. Man will even come to fear science and knowledge, and fear even more the feeling of emptiness within him. … Man, after all, is man. The position and life of God cannot be replaced by any man. Mankind does not just require a fair society in which everyone is well-fed and is equal and free, but the salvation of God and His provision of life to them. Only when man receives the salvation of God and His provision of life to them can the needs, yearning to explore, and spiritual emptiness of man be resolved. If the people of a country or a nation are unable to receive the salvation and care of God, then such a country or nation will tread the road to ruin, toward darkness, and shall be annihilated by God.”
