Life is hard for you? Why, is there anyone for whom it is not hard? And do those in the world really have no troubles? Be patient, and a comforter will come in time. The Lord said, `In your patience possess ye your souls' (Lk. 21:19). If you are unable to do something and your health does not permit it, humble yourself and beg meekly [to be excused] - and above all, be patient. And if you lose patience in some situation, reproach yourself and ask God for help.
As a man cannot remain unscathed who spares his enemy on the field of battle, so a man engaged in spiritual warfare cannot save his soul if he spares his body.
The road into the Kingdom of Heaven was made by the Lord Jesus Christ, and He was the first one who traveled it. The Bible teaches that only he who follows Jesus can reach His Kingdom. But how can one follow Him? Hear what our Savior says about this: Whoever desires to come after Me, let him deny himself, and take up his cross, and follow Me (Mark 8:34). The words whoever desires mean that Christ does not compel anyone to follow Him. He has no need of the unwilling ones, but He desires that each person freely follow Him. Consequently, only those who willingly choose the Savior's path reach the Kingdom of Heaven.
Love sinners, but hate their works, and do not despise them for their faults, lest you be tempted by the same. Remember that you share the earthly nature of Adam and that you are clothed with his infirmity.
How can one say that a man has attained purity? - When he sees all men as being good, and when none appears to him to be unclean and defiled - then he is indeed pure in heart.
Hold faith and humility fast within you; for through them you will find mercy, help, and words spoken by God in the heart, along with a protector who stands beside you both secretly and manifestly.
As for uprooting your passions, begin with self-reproach and with awareness of your own weaknesses; and consider yourself to be deserving of afflictions.
