Genuine holy courage is always united with the feeling of deep humility. A humble person is always ready to endure everything , both internal and external, considering himself to be deserving not only of the sorrows which are sent to him, but even more. It is impossible to upset and confuse a humble person - he is ready for everything, as St.Moses the Black said when they drove him out of the trapeza: I made ready, and I was not troubled (Ps 118:60). And so, let us prepare our souls and hearts with humility, and it will help us to endure every temptation.
St. Nikon
