If there are people and there is God, then there are relationships between God and people. These relationships are changing with time, and mankind's religious conceptions are constantly evolving, constantly improving, becoming more clear and easily understood with the passage of time.
Religious conscience of mankind is not rigid; it is changing all the time, becoming purer and clearer.
God is spirit and part of this spirit lives inside me and gives sense to my life.
There is much good to be learned from the Koran, from the Buddhists, from Confucius, from the Old Testament, from the Indian Upanishads, and from the New Testament. But the closer a religious thinker or philosopher is to us in time, the more he can help us draw from these teachings in the light of our present-day lives.
