Watchfulness and the Jesus Prayer, as I have said, mutually reinforce each other, for close attentiveness goes with constant prayer, while prayer goes with close watchfulness and attentiveness of intellect.
Peter was first given the keys, but then he was allowed to fall into the sin of denying Christ; and so his pride was humbled by his fall. Do not be surprised, then, if after receiving the keys of spiritual knowledge you fall into various evil thoughts. Glorify our Lord, for He alone is wise: through setbacks of this kind He restrains the presumption that we tend to feel because of our advance in the knowledge of God. Trials and temptations are the reins whereby God in His providence restrains our human arrogance.
Often when someone throws a rock at a dog, rather than rushing at the person who threw the stone, the dog will run and bite the stone. We do the same thing. The tempter uses someone else to tempt us, either in word or deed, and, rather than deal with the tempter who threw the stone, we bite the rock, our fellow man that the hater of the good used against us.
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.
If you are praised, be silent. If you are scolded, be silent. If you incur losses, be silent. If you receive profit, be silent. If you are satiated, be silent. If you are hungry, also be silent. And do not be afraid that there will be no fruit when all dies down; there will be! Not everything will die down. Energy will appear; and what energy!
The Lord said, 'When you have done all that is commanded you, say: We are useless servants: we have only done what was our duty' (Luke 17:10). Thus the kingdom of heaven is not a reward for works, but a gift of grace prepared by the Master for His faithful servants.
The heart which is constantly guarded, and is not allowed to receive the forms, images and fantasies of the dark and evil spirits, is conditioned by nature to give birth from within itself to thoughts filled with light. For just as coal engenders a flame, or a flame lights a candle, so will God, who from our baptism dwells in our heart, kindle our mind to contemplation when He finds it free from the winds of evil and protected by the guarding of the intellect.
The hour of death will come upon us, it will come, and we shall not escape it. May the prince of this world and of the air (cf. John 14:30; Eph. 2:2) find our misdeeds few and petty when he comes, so that he will not have good grounds for convicting us. Otherwise we shall weep in vain. 'For that servant who knew his lord's will and did not do it as a servant, shall be beaten with many stripes' (cf. Luke 12:47).
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).
On days when a Saint is celebrated, Christians ought to pray more ardently, with contrition and love, and entreat the Saint to intercede with God for the salvation of their soul. The feast day of every Saint is for Christians a serious reminder of the great sufferings which the Saints experienced for the sake of Christ's faith. They were glorified by God and with glory they received a place in the Kingdom of Heaven. Let us then honor the Saints and invoke their help, in order that they might strengthen us in our prayer. And we may rest assured that our prayer will be listened to by God.
The humility which in due time and by God's grace, after many struggles and tears, is given by heaven to those who seek it is something incompararably stronger and higher than the sense of abasement felt by those who have lapsed from holiness. This higher humility is granted only to those who have attained true perfection and are no longer under the sway of sin.
