"My dearest son, my first instruction is that you should love the Lord your God with all your heart and all your strength, Without this there is no salvation. Keep yourself, my son, from everything that you know displeases God, that is to say, from every mortal sin. You should permit yourself to be tormented by every kind of martyrdom before you would allow yourself to commit a mortal sin.
If the Lord has permitted you to have some trial, bear it willingly and with gratitude, considering that it has happened for your good and that perhaps you well deserved it. If the Lord bestows upon you any kind of prosperity, thank Him humbly and see that you become no worse for it, either through vain pride or anything else, because you ought not to oppose God or offend Him in the matter of His gifts."
~from a spiritual testament of Saint Louis, King of France to his son
