No matter how much we may study, it is not possible to come to know God unless we live according to His commandments, for God is not know by science, but by the Holy Spirit. Many philosophers and learned men came to the belief that God exists, but they did not know God. It is one thing to belief that God exists and another to know Him. If someone has come to know God by the Holy Spirit, his soul will burn with love for God day and night, and his soul cannot be bound to any earthly thing.

Tell everything to your spiritual father, and the Lord will have mercy on you and you will escape delusion. But if you think that you know more about the spiritual life than your spiritual father, and you stop telling him everything about yourself in confession, then you will immediately be allowed to fall into some sort of delusion, in order that you may be corrected.

Christ prayed for those that crucified Him: 'Father, count not this sin against them; they know not what they do.' Archdeacon Stephen prayed for those who stoned him so that the Lord would not judge this sin against them. And so we, if we wish to retain grace, must pray for our enemies. If you do not find pity on a sinner who will suffer in flames, then you do not carry the grace of the Holy Spirit, but rather an evil spirit; and while you yet live, you must free yourself from his clutches through repentance.

The Lord does not show Himself to a proud soul. The proud soul, no matter how many books it reads, will never know God, since by its pride it does not give place for the grace of the Holy Spirit, while God is known only by the humble soul.

When the soul by the Holy Spirit comes to know the Mother of God; when in the Holy Spirit the soul becomes kin to the Apostles, the Prophets, and all the Saints and Righteous Ones, then she is irresistibly drawn to that world, and cannot remain, but is bothered, and thirsts, and cannot cease from prayer, and although the body becomes exhausted and wants to lie down on a bed, even while lying in bed the soul longs for the Lord and the Kingdom of the Saints.

Understand two thoughts, and fear them. One says, "You are a saint," the other, "You won't be saved." Both of these thoughts are from the enemy, and there is no truth in them. But think this way: I am a great sinner, but the Lord is merciful. He loves people very much, and He will forgive my sins.

If a man does not tell everything to his spiritual father, then his path is crooked and does not lead to the Kingdom of Heaven. But the path of one who tells everything leads directly to the Kingdom of Heaven.
