The Lord commands all men to repent (Matt. 4:17), so that even the spiritual and those making progress should not neglect this injunction and fail to give attention to the smallest and most subtle errors.
If we want to do something but cannot, then before God, Who knows our hearts, it is as if we have done it. This is true whether the intended action is good or bad.
If you wish to be saved and 'to come unto the knowledge of the truth' (I Tim. 2:4), endeavor always to transcend sensible things, and through hope alone to cleave to God. Then you will find principalities and powers fighting against you (Eph. 6:12), deflecting you against your will and provoking you to sin. But if you prevail over them through prayer and maintain your hope, you will receive God's grace, and this will deliver you...
Those who have sinned must not despair. Let that never be. For we are condemned not for the multitude of evils, but because we do not want to repent...
The present age is temporal. In comparison with the future one it is like a drop in the oceans. So no longer attach your mind to temporal and earthly things, but to the incorruptible and heavenly things. Let us long with our whole soul for heavenly things, and with God's help we shall obtain them. Let your recollections, says Saint Yperechios, be in the Kingdom of Heaven, and you shall quickly inherit it. So please, my brethren, let us not be negligent and drowsy.
When tested by some trial you should try to find out not why or through whom it came, but only how to endure it gratefully, without distress or rancor.
Those who have sinned must not despair. Let that never be. For we are condemned not for the multitude of evils, but because we do not want to repent...
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.
Comprising one flesh, [the couple] also has a single soul, and their mutual love awakens in them a zeal for piety. For the state of wedlock does not estrange us from God, but rather ties us more closely to Him, for it brings forth a greater impetus to turn to Him. Even under a light breeze, a small boat moves forward…., a light breeze will not move a great ship.... Thus, those not burdened with secular concerns have less need of help from Almighty God, but one who has responsibilities, who looks after his beloved spouse, his estate and his children, traverses a broader sea of life, and has greater need of God’s help. In return [for that help], he himself comes to love God even more.
There is a sin which is always 'unto death' [1 Jn 5:16]; the sin which we have not repented. Even a saint's prayers will not be heard for the unrepented sin. The person who repents correctly does not imagine that his sins are cancelled through his own effort; but knows that through this effort he makes peace with God.
