St. Gregory the Dialogist wrote about what price we have to pay to acquire the Kingdom of Heaven. It has no exact price. Everyone has to give everything he has. The Apostle Peter gave his nets & received the heavenly kingdom; the widow gave two mites; whoever has a million dollars, let him give that; & whoever has nothing, let him give his freedom.
Forgive and pray, in order to live your life serenely. And do not do to others that which you do not want them to do to you, or return the evil which they have done to you.
