If you carry the cross willingly, it will carry and lead you to the desired goal where indeed there shall be no more suffering, but here there shall be. If you carry it unwillingly, you create a burden for yourself and increase the load, though still you have to bear it. If you cast away one cross, you will find another and perhaps a heavier one. Do you expect to escape what no mortal man can ever avoid? Which of the saints was without a cross or trial on this earth? Not even Jesus Christ, our Lord, Whose every hour on earth knew the pain of His passion. “It behooveth Christ to suffer,and to rise again from the dead, . . . and so enter into his glory. How is it that you look for another way than this, the royal way of the holy cross?
The whole life of Christ was a cross and a martyrdom, and do you seek rest and enjoyment for yourself? You deceive yourself, you are mistaken if you seek anything but to suffer, for this mortal life is full of miseries and marked with crosses on all sides. Indeed, the more spiritual progress a person makes, so much heavier will he frequently find the cross, because as his love increases, the pain of his exile also increases.
Yet such a man, though afflicted in many ways, is not without hope of consolation, because he knows that great reward is coming to him for bearing his cross. And when he carries it willingly, every pang of tribulation is changed into hope of solace from God. Besides, the more the flesh is distressed by affliction, so much the more is the spirit strengthened by inward grace. Not infrequently a man is so strengthened by his love of trials and hardship in his desire to conform to the cross of Christ, that he does not wish to be without sorrow or pain, since he believes he will be the more acceptable to God if he is able to endure more and more grievous things for His sake.
It is the grace of Christ, and not the virtue of man, which can and does bring it about that through fervor of spirit frail flesh learns to love and to gain what it naturally hates and shuns.
-Thomas à Kempis, Imitation of Christ, chapter 12.
