January 28th is the feast of St Isaac the Syrian.
Gratefulness on the part of the recipient spurs on the giver to bestow gifts larger than before….
The sick one who is acquainted with his sickness is easily to be cured; and he who confesses his pain is near to health.
Many are the pains of the hard heart; and when the sick one resists the physician, his torments will be augmented.
There is no sin which cannot be pardoned except that one which lacks repentance, and there is no gift which is not augmented save that which remains without acknowledgement.
For the portion of the fool is small in his eyes.
Think constantly of those who are superior to you in excellence, so you may see yourself at all times as being less than they are.
And be aware at all times of the heavy troubles of those whose vexations are difficult and serious, so that you may become grateful for your own small ones and be able to bear them with joy.
When you are in a state of subjection and are languid and dejected, and thou art hound and fettered before your foe in mournful wretchedness and laborious service of sin, then recall to mind the previous times of firmness….
Then, by these and similar recollections, your soul will be aroused as from the depth and be clad with the flame of zeal; and it will rise from its immersion as if from the dead, and stretch itself and return to its former state, in hot strife against Satan and sin….
Be a persecutor of yourself; then your foe will be driven away from you. Be on peaceful terms with your soul; then heaven and earth will be on peaceful terms with you.
Be zealous to enter the treasury within you; then you will see that which is in heaven. For the former and the latter are one, and, entering, you will see both.
The ladder unto the Kingdom is hidden within you and within your soul.
Dive into yourself, freed from sin; there you wilt find steps along which you can ascend.
What the things of the world-to-be are, the scriptures do not explain. How we may acquire the faculty to perceive their delight even now, without change of nature or local transition, they teach us plainly.
Though they call these things by beloved names of glorious things which are delightful and esteemed by us, in order to spur us on, still by saying that “the eye has not seen, nor the ear heard” (1 Cor.2:9) and so on, they show us that the things-to-be are not equal to any of the present things, by their being incomprehensible.
