Mark the Evangelist quotes:

A humble man who lives a spiritual life, when he reads the Holy Scriptures, while relate all things to himself and not to others.

And they went forth and preached everywhere, while the Lord worked with them and confirmed the message by the signs that attended it.

If the criminal will not keep his gains for ever and his victim will not always suffer want, surely man passes like a shadow and troubles himself in vain.

Unless a man gives himself entirely to the Cross, in a spirit of humility and self-abasement; unless he casts himself down to be trampled underfoot by all and despised, accepting injustice, contempt and mockery; unless he undergoes all these things with joy for the sake of the Lord, not claiming any kind of human reward whatsoever - glory or honor or earthly pleasures - he cannot become a true Christian.

Do not become a disciple of one who praises himself, in case you learn pride instead of humility.
