Isaac of Nineveh

In his own words on Isaiah

• Isaiah 1:15

  Whenever [those who are lazy] pray to Him, He does not quickly hearken to them, but waits until they grow weary and have learned in no uncertain manner that these things befell them because of their slothfulness and negligence.… Even if this was said of others also, nonetheless it is written especially about those who have abandoned the way of the Lord.

  ASCETICAL HOMILIES 5

• Isaiah 43:2

  "If thou go through fire, thou shalt not be burned, and the rivers shall not flow over thee." Faith has many times worked such things before the eyes of all creation. If knowledge were given the opportunity to attempt such things, it would in no wise be persuaded. For it is by faith that men have entered into flames and bridled the burning power of the fire, walking unharmed through the midst thereof, and they have trodden upon the back of the sea as upon dry land. All these are above nature and opposed to the modes of knowledge.

  ASCETICAL HOMILIES 52

• Isaiah 53:2

  Therefore, beloved, have in your mind God's providence (which from the beginning until now is dispensed with foreknowledge) as some excellent medicine for weakened eyes, and keep its recollection with you at all times. Ponder, consider, and be taught by these things, that you may learn to hold the remembrance of the greatness of God's honour in your soul, and thus find life eternal for your soul in Jesus Christ our Lord, Who is become "the Mediator between God and men," as being the Uniter in His two natures. The orders of the angels cannot approach the glory that surrounds the throne of His majesty, yet He has appeared in the world for our sake in a mean and humble form, as [Isaiah] said: "We beheld Him, that He had no form nor beauty." It is He that, being invisible to all created nature, put on a body and fulfilled the economy for the salvation and life of all the nations that were cleansed by Him, and to Him be glory and dominion unto the ages of ages. Amen.

  ASCETICAL HOMILIES 3

• Isaiah 54:13

  In the same way He wrote through the prophets, for "He put His laws into their minds and He wrote them on their hearts," so that they should all be "taught of God."If we now set aright our disgraceful lives with the aid of writings on account of the rationality that our nature received from the beginning, how much shall we turn aside from God if we show contempt for the natural book of the heart, the book written by Moses and the prophets, and the light of our Savior's Gospel of life! Hence we shall bring capital punishment upon ourselves if we gain no help from the hidden book, or from the visible one, or from the Gospel of the life-giving commandments of our Lord Jesus Christ. Not even the man who toils and exerts himself in prayer, reading, divine vision, and insight, will make progress in the truth and gain an illumined intellect, unless he aims the intention of his mind toward the strength of what is written by the Spirit on the book of his heart. The veil of the passions that overlays our heart prevents us from truly beholding that which is written on our heart by the Spirit. When we pray, read, and sing praises, we float over the surface of our heart without truly perceiving what lies within. But if we raise the veil of the passions by observing the commandments, then with the eye of the spirit we shall see the truth that is imprinted in our heart.

  BOOK OF GRACE 5:74-77

• Isaiah 58:3

  Ye offer [your own wills] as whole burnt offerings unto idols; and unto the wretched thoughts, that ye reckon in yourselves as gods, ye daily sacrifice your free will, a thing more precious than all incense, which ye ought rather to consecrate unto Me by your good works and your purity of conscience.

  ASCETICAL HOMILIES 6

• Isaiah 58:9

  Whenever you keep the ways of the Lord and do His will, then put your hope in the Lord and call on Him.…When temptation overtakes the iniquitous person, he has no confidence wherewith to call upon God, nor to expect salvation from Him, since in the days of his ease he stood aloof from God's will.

  ASCETICAL HOMILIES 5

• Isaiah 59:2

  But since we say that God is plenteous in mercy, why is it that when amidst temptations we unceasingly knock and pray, we are not heard and He disregards our prayer? This we are clearly taught by the Prophet when he says, "The Lord's hand is not little, that it cannot save; nor is He hard of hearing, that He cannot hear: but our sins have separated us from Him." … Remember God at all times, and He will remember you whenever you fall into evils.

  ASCETICAL HOMILIES 5

• Isaiah 61:1

  Do not fall into despair because of stumblings. I do not mean that you should not feel contrition for [your sins], but that you should not think them incurable. For it is more expedient to be bruised than dead. There is, indeed, a Healer for the person who has stumbled, even He Who on the Cross asked that mercy be shown to His crucifiers, He Who pardoned His murderers while He hung on the Cross. … For a brief moment of mourning He pardoned Simon, who had denied Him.… Christ came in behalf of sinners, to heal the broken of heart and to bandage their wounds. "The Spirit of the Lord," He says, "is upon Me, to preach good tidings to the poor." … And the Apostle says in his epistle, "Jesus Christ came into the world to save sinners."
