Faith is an eye that enlightens every conscience, and imparts understanding; for the Prophet saith, And if ye believe not, ye shall not understand (Is. vii, 9).
I beseech you, put this to the test. When a man affronts you or brings dishonor on your head, or takes what is yours, or persecutes the Church, pray to the Lord, saying: 'O Lord, we are all Thy creatures. Have pity on Thy servants and turn their hearts to repentance,' and you will be aware of grace in your soul. To begin with, constrain your heart to love enemies, and the Lord, seeing your good will, will help you in all things, and experience itself will show you the way. But the man who thinks with malice of his enemies has not God's love within him, and does not know God.
Do you wish God to hear your prayer immediately, brother? When you lift your hands up to heaven, pray first of all, with your heart, for your enemies and God will grant you speedily whatever else you request.
If you will pray for your enemies, peace will come to you; but when you can love your enemies - know that a great measure of the grace of God dwells in you, though I do not say perfect grace as yet, but sufficient for salvation. Whereas if you revile your enemies, it means there is an evil spirit living in you and bringing evil thoughts into your heart, for, in the words of the Lord, out of the heart proceed evil thoughts - or good thoughts.
There is nothing impossible unto those who believe; lively and unshaken faith can accomplish great miracles in the twinkling of an eye. Besides, even without our sincere and firm faith, miracles are accomplished, such as the miracles of the sacraments; for God's Mystery is always accomplished, even though we were incredulous or unbelieving at the time of its celebration. 'Shall their unbelief make the faith of God without effect?' (Rom. 3:3). Our wickedness shall not overpower the unspeakable goodness and mercy of God; our dullness shall not overpower God's wisdom, nor our infirmity God's omnipotence.
If you harbor rancor against anybody, pray for him and you will prevent the passion from being aroused; for by means of prayer you will separate your resentment from the thought of the wrong he has done you. When you have become loving and compassionate towards him, you will wipe the passion completely from your soul.
Faith is the sincere confession that God, Who is worshipped in the Trinity, Who created all things and provides for all, saves us who are fallen, through the power of the death on the Cross of the incarnate Son of God, by the grace of the Most Holy Spirit in His Holy Church. The beginnings of renewal, which are established in this life, will appear in all their glory in the future age, in a way that the mind cannot comprehend nor the tongue express.
Faith is truly a gift, gained for us through Christ's advent. But this does not abolish our freedom or responsibility. God desires of us not only faith but action too.
The good man thinks to himself in this wise: Every one who has strayed from the truth brings destruction on himself and is therefore to be pitied. But of course the man who has not learned the love of the Holy Spirit will not pray for his enemies. The man who has learned love from the Holy Spirit sorrows all his life over those who are not saved, and sheds abundant tears for the people, and the grace of God gives him strength to love his enemies.
If you fast regularly, do not be inflated with pride; if you think highly of yourself because of it, then you had better eat meat. It is better for a man to eat meat than to be inflated with pride and glorify himself.
The Lord taught me to love my enemies. Without the grace of God we cannot love our enemies. Only the Holy Spirit teaches love, and then even devils arouse our pity because they have fallen from good, and lost humility in God.
Someone may say: 'I have faith, and faith suffices for salvation.' St. James gives him the answer: 'Even the demons believe, and shudder. Faith without works is dead.' (James 2:17-19)
