We must always pray to the Lord to tell us what to do, and the Lord will not let us go astray. Adam was not wise enough to ask the Lord about the fruit which Eve gave him, and so he lost paradise.
The Saints were people just like ourselves. Many of them started with grievous sins but through repentance they attained the Kingdom of Heaven. And every one who comes to the Kingdom of Heaven does so through repentance which the Merciful Lord granted us by His sufferings. In the Kingdom of Heaven, the holy Saints look upon the glory of our Lord Jesus Christ; but through the Holy Spirit they see, too, the sufferings of men on earth. The Lord gave them such great grace that they embrace the whole world with their love. They see and know how we languish in affliction, how our hearts have withered within us, how despondency has fettered our souls, and they never cease to intercede for us to God.
The practice of the prayer of Jesus holy David, or more accurately the Holy Spirit by the mouth of David, offers to all Christians without exception: 'The kings of the earth and all people, princes and all judges of the earth, young men and maidens - let elders with the young praise the name of the Lord, for His name alone is exalted (PS. 148:11-13).' A literal understanding of the states enumerated here would be perfectly permissible, but their essential meaning is spiritual.
Only to the humble does the Lord reveal Himself in the Holy Spirit, but if we do not humble ourselves we shall not see God. Humility is the light in which we may behold the Light which is God, as the Psalmist sang: 'In Thy light we shall see light.'
When you intend to do something and see that your thought is perturbed, and if after invoking God's Name it remains perturbed even by a hair's breadth, know from this that the action you mean to commit is from the evil one and refrain from commiting it. For nothing done with perturbation is pleasing to God.
But a sober and prudent man who desires to be saved, when he sees from what it is that he suffers harm, carefully preserves himself from evil remembrances, is not drawn into passionate thoughts, avoids meetings and conversations with those for whom he feels attraction and avoids every occasion for sin, fearing lest he himself ignite a fire within himself. This is the warfare which proceeds from one’s own lust, which a man brings on himself
To many people the Saints seem far from us. But the Saints are far only from those who have taken themselves away from them, and are very close to those who keep Christ’s commandments and possess the grace of the Holy Spirit.
If you wish to be delivered from shameful passions, do not behave with anyone familiarly, especially with those toward whom your heart is inclined by a lustful passion; through this you will be delivered also from vainglory. For in vainglory is involved the pleasing of men, in the pleasing of men is involved familiarity of behavior, and familiarity of behavior is the mother of all passions.
Understand me. It is so simple. People who do not know God, or who go against Him, are to be pitied; the heart sorrows for them and the eye weeps. Both paradise and torment are clearly visible to us: We know this through the Holy Spirit. And did not the Lord Himself say, 'The kingdom of God is within you?' Thus eternal life has its beginning here in this life; and it is here that we sow the seeds of eternal torment.
The Holy Fathers teach us how to become familiar with the Gospel, how to read it and how to understand it, what helps and what opposes its understanding. Therefore, at first you must devote more time to reading the Holy Fathers...
