Entry in Tolstoy's Diary http://www.linguadex.com/tolstoy/chapter1.htm (1 November 1910)
Context: God is the infinite ALL. Man is only a finite manifestation of Him.
Or better yet:
God is that infinite All of which man knows himself to be a finite part.
God alone exists truly. Man manifests Him in time, space and matter. The more God's manifestation in man (life) unites with the manifestations (lives) of other beings, the more man exists. This union with the lives of other beings is accomplished through love.
God is not love, but the more there is of love, the more man manifests God, and the more he truly exists...
We acknowledge God only when we are conscious of His manifestation in us. All conclusions and guidelines based on this consciousness should fully satisfy both our desire to know God as such as well as our desire to live a life based on this recognition.

Founding Address (1876), Life and Destiny (1913)
Context: Let us learn from the lips of death the lessons of life. Let us live truly while we live, live for what is true and good and lasting. And let the memory of our dead help us to do this. For they are not wholly separated from us, if we remain loyal to them. In spirit they are with us. And we may think of them as silent, invisible, but real presences in our households.
