This is a series of lectures that Soloviev gave that read like Scripture. Tolstoy and Dostevyesky attended the lectures. They are amazing!
Essentially a work of moral theology/philosophy packed with great insights. I quote from this work in my Lenten Meditation for the First Sunday of Lent here:
Solovyov posits two rules in this regard:
"Have God in you." (God wants to be in communion with us. He wants to fulfill the desire He has placed in our hearts for Him.)
"Regard everything in God's way."(And here Solovyov means "everything," even evil, of which he says:"We must regard evil in God's way, i.e. without being indifferent to it, we must rise above absolute opposition to it and allow it--when it does not proceed from us--as means of perfection, in so far as a greater good can be derived from it. (The Justification of the Good" )
