He who wishes to tear up the account of his sins and to be inscribed in the Divine book of the saved, can find for this purpose no better means than obedience.
He who reveres the Lord does what is commanded, and if he commits some sin or disobeys Him, endures whatever he has to suffer for this as being his desert.
St. Peter of Damascus teaches, 'When joy comes, represent sorrow to yourself; and when you are encompassed by sorrow, try to awaken joy.' Thus you will be safeguarded both against deception and against despair.
Do not be despondent when fighting against the incorporeal enemy, but even in the midst of your afflictions and oppression praise the Lord, Who has found you worthy to suffer for Him, by struggling against the subtlety of the serpent, and to be wounded for Him at every hour; for had you not lived piously, and endeavored to become united to God, the enemy would not have attacked and tormented you.
There is no shorter ascent to the royal and Divine mansions...than through subduing the five passions hostile to obedience, namely: disobedience, argumentativeness, self-gratification, self-justification and pernicious high opinion of oneself...Disobedience is the mouth of hell; argumentativeness its tongue, whetted like a sword; self-gratification is its sharp teeth; self-justification its throat; high opinion of oneself, which casts one into hell, is the belching of its all-devouring belly. But he who, through obedience, conquers the first, by one stroke cuts off all the rest and with one stride reaches heaven.
Train yourself to cut off an intrusive thought immediately… Be at pains over this, so that you acquire the habit. The soul is a creature of habit: according to the habit you have acquired, so will you act all the rest of your life.
In order, then, that Christ may win us all unto obedience, He promises us surpassing honors, and deigns us the highest love, saving, `My mother and My brethren are those who hear the word of God and do it.' For who among men is so obdurate and ungentle, as to refuse to honor, and accord the most complete love to his mother and brethren? For the all-powerful law of nature, even without our will, obliges us to this. When, therefore, bowing our neck to the Savior's commands, we become His followers, and so are in the relation of a mother and brethren to Him, how does He regard us before God's judgment seat? Is it not with gentleness and love? What doubt can there be of this?: And what is comparable to this honor and goodness? What is there worthy of being matched with a gift thus splendid and desirable?
It is, indeed, impossible for the mind not to be troubled by thoughts, but accepting them or rejecting them is possible for everyone who makes an effort...therefore we practice the frequent reading of Scripture, so that we may be open to a spiritual point of view. For this reason we frequently chant the psalms, so that we may continually grow in compunction. For this reason we are diligent in vigils, fasting, and praying, so that the mind which has been stretched to its limits may not taste earthly things but contemplate heavenly ones. When these things cease because negligence has crept in again, then, it is inevitable that the mind, by the accumulated filth of the vices, will soon turn in a carnal direction and fall.
The fathers have laid down that psalmody is a weapon, and prayer is a wall, and honest tears are a bath; but blessed obedience in their judgment is confession of faith, without which no one subject to the passions will see the Lord.
The day will come when you are toiling at self-observation and self-constraint, and the adversary will come up and mumble in your ear, 'This will all happen eventually. You’ve been working hard, now take it easy a little bit!' This is such a tempting suggestion that it does not immediately occur to you that you should counter it, or that it is so bad that however little you give in to it, it will cause such inner disturbance. Indulging yourself is just like a tiny hole in a dam. Once a hole has formed, the dam cannot hold; the water will inevitably destroy it. Indulgence does the same thing inside of us; everything will be dispersed, so it will be necessary to start all over again to restore ourselves. Fear this as your most evil enemy, although he speaks with the sweetest words.
First of all it must be understood that it is the duty of all Christians - especially of those whose calling dedicates them to the spiritual life - to strive always and in every way to be united with God, their creator, lover, benefactor, and their supreme good, by whom and for whom they were created. This is because the center and the final purpose of the soul, which God created, must be God Himself alone, and nothing else - God from whom the soul has received its life and its nature, and for whom it must eternally live. For all visible things on earth which are lovable and desirable - riches, glory, wife, children, in a word everything of this world that is beautiful, sweet, and attractive - belong not to the soul but only to the body, and being temporary, will pass away as quickly as a shadow. But the soul, being eternal by its nature, can attain eternal than all beauty, sweetness, and loveliness, and He is its natural home, whence it came and whither it must return. For as the flesh coming from the earth returns to the earth, so the soul coming from God returns to God and dwells in Him. For the soul was created by God in order to dwell in Him forever; therefore in this temporary life we must diligently seek union with God, in order to be accounted worthy to be with Him and in Him eternally in the future life.
Obedience is the medicine compounded of virtues, giving life to those who drink it, and the knife which, with one cut, cleans festering wounds. A man who, in faith and simplicity, has chosen to wield this knife, at once cuts off all passions, more completely than anyone...
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.
