By holy baptism original sin is expunged, as also sins committed before baptism. It also eliminates the violent power sin has over us till rebirth; it gives us the grace of the Holy Spirit by which we are united with God in Christ, and we receive power to subdue and conquer sin. For the simple reason that we are not delivered from the struggle with sin, we cannot be entirely free from sin during the whole of our earthly life, and even the righteous man may fall seven times (i.e. often) and rise again by repentance, says Scripture (Prov. 24:16). He falls on account of his weakness and limitations, because he does not always notice sin which subtly and imperceptibly rears its head from his fallen nature, and which is artfully and imperceptibly offered and suggested by fallen spirits. Repentance becomes his secure possession, his constant weapon, his invaluable treasure. By repentance the righteous man maintains his fellowship with Christ. He is healed by repentance from the wounds caused by sin.
In order to remain in vigilance, it is necessary to guard the freshness and brightness of the mind with all care. The mind becomes darkened from imprudent use of food, drink and sleep, from much talking, from distraction and from worldly cares. Attend to yourselves, said the Lord, be on your guard and take care that your hearts are never weighed down, dulled and depressed by self-indulgence, overeating and drinking, or worldly cares and pleasures, lest that day (the day of Christ's dread judgment, the last day of the world) catch you unawares. For it will spring like a trap upon all who are living on the face of the earth. So watch and pray at all times for the strength to escape or survive all that is going to happen, and to stand before the Son of Man.
A mind that dwells on everyday matters of life and vain things disperses the soul. One should turn inwardly, looking at the soul’s uncultivated vineyard, weeding it of all evil thorns and planting virtues there instead. But be wary, for this type of work is not easy at all. It requires perseverance and much patience. One will be confronted with a multitude of difficulties. Various writings of the Fathers are very helpful, and in our days are available by the dozens. In them one can find anything his heart desires, and anything it needs. The Fathers will lead you on the right spiritual path, if only you read them with humility and prayer.
Unfortunately today sin superabounded and superexceeded and people who call light darkness and darkness light; truth falsehood and falsehood truth; sweet bitter and bitter sweet; good evil and evil good. We find these people in all ranks of society except for a few select people, for whose sake may the Lord have mercy on us.
St. John Climacus was asked if there are reliable signs by which it's possible to know whether a soul is drawing near to God or moving away from Him. After all, regarding ordinary things there are clear signs as to whether they're good or not. When, for instance, cabbage, meat or fish begins to rot, it's easy to notice it, since the rotting object begins to give off a foul odor, the color and taste change, and its external appearance witnesses to its deterioration. Well, and what about the soul? After all, it's bodiless and can't give off a bad smell or change its appearance. To this question the Holy Father replies, 'A sure sign of the deadening of the soul is the avoidance of church services.'
My child, man's life is full of sorrow because he is in exile. Do not seek perfect rest. Since our Christ bore His Cross, we shall bear ours, too. If we endure all afflictions, we shall receive grace from the Lord. The Lord allows us to be tempted, so that He can test the zeal and love we have for Him. Therefore, patience is needed. Without patience a person does not obtain experience, acquire spiritual knowledge, or attain any measure of virtue and perfection.
When can someone understand human suffering? When he also suffers. When he goes through the same, he learns and understands the other person's suffering. Otherwise, he is callous and is not grieved, unless he happens to have a good nature. But all natural attributes merit neither honor nor dishonor; achievements and falls depend on our own free will.
As soon as you realize that you have sinned against the Lord, add no more wounds to your bruises. But if as a human you fall again, don't get despondent, don't despair. For how will the living Lord, Who told Peter to forgive seventy times seven in a day, not forgive us?
