Whoever will not love his enemies cannot know the Lord and the sweetness of the Holy Spirit. The Holy Spirit teaches us to love our enemies in such way that we pity their souls as if they were our own children.

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.

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.

A certain monk told me that when he was very sick, his mother said to his father, "How our little boy is suffering. I would gladly give myself to be cut up into pieces if that would ease his suffering." Such is the love of God for people. He pitied people so much that he wanted to suffer for them, like their own mother, and even more. But no one can understand this great love without the grace of the Holy Spirit.

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.

Consider that the Holy Spirit lives in the spiritual father, and He will tell you what to do. But if you think that the spiritual father live negligently, and that the Holy Spirit can't live in him, you will suffer mightily for such a thought, and the Lord will humble you, and you will straightway fall into delusion.

Each of us can discuss God inasmuch as he has known the grace of the Holy Spirit; for how can we think of or discuss what we haven't seen, or haven't head of, or don't know? The saints say that they have seen God, but there are people who say that there is no God. Clearly, they say this because they haven't known God, but this does not at all mean that He is not. The saints speak of that which they have truly seen and know.
