God is truth and light. God’s judgment is nothing else than our coming into contact with truth and light. In the day of the Great Judgment all men will appear naked before this penetrating light of truth. The ‘books’ will be opened. What are these ‘books’? They are our hearts. Our hearts will be opened by the penetrating light of God, and what is in these hearts will be revealed. If in those hearts there is love for God, those hearts will rejoice in seeing God’s light. If, on the contrary, there is hatred for God in those hearts, these men will suffer by receiving on their opened hearts this penetrating light of truth which they detested all their life.
So that which will differentiate between one man and another will not be a decision of God, a reward or a punishment from Him, but that which was in each one’s heart; what was there during all our life will be revealed in the Day of Judgment. If there is a reward and a punishment in this revelation – and there really is – it does not come from God but from the love or hate which reigns in our heart. Love has bliss in it, hatred has despair, bitterness, grief, affliction, wickedness, agitation, confusion, darkness, and all the other interior conditions which compose hell.
