A man who considers himself the master of his own life can never be humble, because he thinks that he has no obligation to anyone. The man who considers service to God to be the purpose of his life is always humble, because he feels that he has never fulfilled his obligations.
And the apostles said unto the Lord, Increase our faith. And the Lord said, If ye had faith as a grain of mustard seed, ye might say unto this sycamine tree, Be thou plucked up by the root, and be thou planted in the sea; and it should obey you. But which of you, having a servant plowing or feeding cattle, will say unto him by and by, when he is come from the field, Go and sit down to meat? And will not rather say unto him, Make ready wherewith I may sup, and gird thyself, and serve me, till I have eaten and drunken; and afterward thou shalt eat and drink? Doth he thank that servant because he did the things that were commanded him? I trow not. So like-wise ye, when ye shall have done all those things which are commanded you, say, We are unprofitable servants: we have done that which was our duty to do.
— Luke 17:5-10
Truly kind people forget the good things they have done in the past. They are so involved in the things they do now that they forget the things they have done before.
— Chinese Wisdom
The better a person knows himself, the smaller and less significant he seems to himself, and the higher he elevates himself toward God.
— Thomas A Kempis
