SO GOOD QUOTES

So if a man does not watch himself well, he may begin some activity with the sole purpose of pleasing the Lord, but later, little by little, introduce into it a self-interest, which makes him find in it also a satisfaction of his own desires, and this to such an extent that the will of God becomes completely forgotten. Then he becomes so tightly bound by enjoyment of the work, that if God Himself were to hinder him in this practice, either through some illness, or through temptations from men or demons, or by some other means, he is filled with indignation, often blames one man or another for having interfered in the course of things he so loves, and sometimes even murmurs against God Himself. This is a sure sign that the disposition of his heart did not come from God, but has sprung from the rotten and corrupted root of self-love.
