The enemy is within ourselves. An invisible war is taking place within us. If interior evil is defeated, then the external, weaker, foe will surrender.
When a man walks the straight path, he does not have a cross. But when he begins to step away from one side to another, then various circumstances arise that push him back onto a right path. These pushes comprise a man's cross. They vary, of course, according to what each individual needs.
The belly when filled with all kinds of food gives birth to seeds of wantonness, nor can the mind, when choked with the weight of food, keep the guidance and government of the thoughts. For not only is drunkenness with wine wont to intoxicate the mind, but excess of all kinds of food makes it weak and uncertain, and robs it of all its power of pure and clear contemplation. The cause of the overthrow and wantonness of Sodom was not drunkenness through wine, but fullness of bread. Hear the Lord rebuking Jerusalem through the prophet. 'For how did thy sister Sodom sin, except in that she ate her bread in fullness and abundance?' (Ezek. xvi. 49)
We must with unflagging zeal and care give ourselves to the pursuit of virtue, and constantly occupy ourselves in its practice, lest at any time progress may cease, and regress immediately take its place.... To cease to acquire means to lose, for the will which goes no longer forward will not be far from peril of falling back.
No virtue makes flesh-bound man so like a spiritual angel as does self-restraint, for it enables those still living on earth to become, as the Apostle says, 'citizens of heaven' (cf. Phil. 3:20).
'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.'
It is impossible for the mind to escape disturbing thoughts, but it is possible, for any who take sufficient care, either to admit them or reject them.
If we abandon our own desires and opinions, and endeavor to fulfill God’s wishes and understanding, we will save ourselves, no matter what our position, no matter what our circumstance. But if we cling to our own desires and opinions, neither position nor circumstance will be of help. Even in Paradise, Eve transgressed God’s commandment, and life with the Savior Himself brought the unfortunate Judas no good. As we read in the Holy Gospels, we require patience and an inclination to pious living.
The full and complete definition of repentance is that we never again allow in ourselves the sins of which we repent, or whereby our conscience is stung. The mark of satisfaction and forgiveness is when we have driven out from our hearts all desire for them.
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.
Every Christian is obligated according to his strength and station to labor for the good of others, but with the condition that it all be timely and orderly, and that the success of our labors represents God and His holy will.
