John Of Kronstadt. Knowledge of God and Self-Knowledge Acquired from Experience (№ 424141)

Human! you are not grateful and evil in relation to God; you do not know how to use the mercies of God, and you do not want to deserve them by devotion to His all-good will, you do not want to endure the slightest test from His benevolent goodness. You are all around in the mercy of God. The devil looks at you with envy and says to God: this person will only bless You in the face. But touch only his property, especially his bones, his health: and then it will be obvious that he blesses (praises, glorifies) You only for Your gifts, and in misfortune he will murmur against You, blaspheme You. And what? About misfortune! It often happens that way. How the matter touches your self-denial, how it takes a few hours or days of patience from you, how it happens to lose something: then it really turns out that you are only able to thank God in happiness, and in misfortune you grumble. Our original enemy, to our shame, remains here in fact right.
