Grumbling is caused by misery and it can be put aside by doxology (giving praise). Grumbling begets grumbling and doxology begets doxology. when someone doesn’t grumble over a problem troubling him, but rather praises God, then the devil gets frustrated and goes off to someone else who grumbles, in order to cause everything to go even worse for him. You see, the more one grumbles, the more one falls into ruin.
Sometimes the devil deceives us and makes us unable to be pleased with anything; however, one can celebrate all things in a spiritual manner, with doxology, and secure God’s constant blessing.
“Let no one deceive you, brother: without holiness, as the apostle says, no one can see God (cf. Heb. 12:14).
For the Lord, who is more than holy and beyond all purity, will not appear to an impure person.
Just as he who loves father or mother, daughter or son (cf. Matt. 10:37) more than the Lord is unworthy of Him, so is he who loves anything transient and material.
Even more unworthy is the person who chooses foul and fetid sin to preference to love for the Lord; for God rejects whoever does not repudiate all filthiness: ‘Corruption does not inherit incorruption’ (1 Cor. 15:50). ”

“A blind person who undertakes to guide others is a deceiver plunging into the pit of destruction those who follow him. As the Lord said: ‘if the blind lead the blind, both will fall into the pit’ (Matt. 25:14).”

“The leaders of any given evil heresy also attempt to interpret their writings, but their purpose is to harm their followers and deny that truth which is in accordance with piety, using the words of the Spirit against the Spirit. The words of the gospel of grace are lofty and suitable for mature ears and minds, but these words too our God-bearing Fathers softened in their own mouths, making them appropriate for those of us who are less than perfect, just as mothers devoted to their children chew solid food and render it serviceable and easy to take for babies still at the breast. The moisture in their mothers’ mouth is nourishment for the children, and the thoughts in the hearts of our God-bearing Fathers are suitable food for souls that listen and obey The mouths of evil, disreputable men, however, are full of deadly poison which, when mixed with the words of life, makes even them lethal for careless listeners.”
+ St. Gregory of Palamas, Homily 34, On the Holy Transfiguration of Our Lord and God and Savior Jesus
Just as the fishermen hide the hook with bait and covertly hook the fish, similarly, the crafty allies of the heresies cover their evil teachings and corrupt understanding with pietism and hook the more simple, bringing them to spiritual death.
+ St. Isidore of Pelusium (Letter to Timothy the Reader, PG, 78:252)
“Implore God with prayers and tears to send you a guide who is dispassionate and holy. But you yourself should also study the divine writings – especially the works of the fathers that deal with the practice of the virtues – so that you can compare the teachings of your master with them; for thus you will see and observe them as in a mirror. Take to heart and keep in mind those of his teachings that agree with the divine writings, but separate out and reject those that are false and incongruent. Otherwise you will be led astray. For in these days there are all too many deceivers and false prophets. ”
