A soul that is nurtured by hatred toward man can not be at peace with God, Who has said: If you forgive not men their sins, neither shall your Father forgive your sins (Matt. 6:15). If a man does not want to be reconciled, you must at least guard yourself from hating, praying with a pure heart for him, and speaking no evil of him.
Maximus the ConfessorHe who has realized love for God in his heart is tireless in his pursuit of the Lord his God, and bears every hardship, reproach and insult nobly, never thinking the least evil of anyone.
Maximus the ConfessorA pure heart is perhaps one which has no natural propulsion towards anything in any manner whatsoever. When in its extreme simplicity such a heart has become like a writing-tablet beautifully smoothed and polished, God comes to dwell in it and writes there His own laws.
Maximus the ConfessorHe has as yet no perfect love, whose disposition towards men depends on what they are like, loving one and despising another for this or that, or sometimes loving, sometimes hating one and the same man. Blessed is the man who can love all men equally.
Maximus the ConfessorEvery genuine confession humbles the soul. When it takes the form of thanksgiving, it teaches the soul that it has been delivered by the grace of God.
Maximus the Confessor...the Lord said as He drew near His passion, 'Now is the Son of man glorified, and God is glorified in Him. If God is glorified in Him, God will also glorify Him in Himself; and He will glorify Him at once' (Jn. 13:31-32). From This it is clear that divine gifts follow sufferings endured for the sake of virtue.
