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.
In Christianity truth is not a philosophical concept nor is it a theory, a teaching, or a system, but rather, it is the living theanthropic hypostasis - the historical Jesus Christ (John 14:6). Before Christ men could only conjecture about the Truth since they did not possess it. With Christ as the incarnate divine Logos the eternally complete divine Truth enters into the world. For this reason the Gospel says: 'Truth came by Jesus Christ' (John 1:17).
Do not neglect the practice of the virtues; if you do, your spiritual knowledge will decrease, and when famine occurs you will go down into Egypt (Genesis 41:57, 46:6).
'God does not create crosses for people ie cleansing spiritual and physical sufferings. And however heavy that cross may be for that individual, the tree that produces its timber grows from the soil of his heart.' The Starets also said: 'If a person walks a straight path, for him there is no cross. However, when he starts to lurch from one side to the other, then different circumstances appear which push him back onto the right track. These elements constitute a cross for a person. Of course they occur differently, according to the individual’s need.' 'Sometimes The cross is a mental one, confusing the individual with sinful thoughts. But the person is not at fault if he doesn’t accede to them. The Starets cited an example: ‘ Once a female ascetic was agitated for a long period over having unchaste thoughts. When Christ appeared and drove them away from her, she cried out to Him: ‘Sweet Jesus, where were You up to this time?’ Christ replied: ‘I was in your heart.’ She said: ‘How can that be? But my heart was filled with unchaste thoughts.’ And Christ said to her: ‘Therefore understand that I was in your heart, and that you had no disposition toward those unclean thoughts but more so, endeavored to liberate yourself from them. Not being able to do so, you suffered over them, thereby preparing a place for me in your heart.’ 'Sometimes, suffering is sent to an innocent person, so that he, as with the example of Christ, suffers for others. Christ Himself suffered for people. Likewise, His Apostles were tortured for the Church and people. To have absolute love means to suffer for your close ones.'
A great effort and much toil are needed in prayer before we can reach a state in which our mind is no longer troubled, and so attain the inward heaven of the heart where Christ dwells. As St. Paul says, 'Do you not realize that Christ dwells within you, unless you are worthless?' (cf. 2 Cor. 13:5).
Suppose you have ordered yourself not to eat fish; you will find that the enemy continually makes you long to eat it. You are filled with an uncontrollable desire for the thing that is forbidden. In this way you can see how Adam's fall typifies what happens to all of us. Because he was told not to eat from a particular tree, he felt irresistibly attracted to the one thing that was forbidden him.
