VERY soon your life here will end; consider, then, what may be in store for you elsewhere. Today we live; tomorrow we die and are quickly forgotten. Oh, the dullness and hardness of a heart which looks only to the present instead of preparing for that which is to come!
Therefore, in every deed and every thought, act as though you were to die this very day. If you had a good conscience you would not fear death very much. It is better to avoid sin than to fear death. If you are not prepared today, how will you be prepared tomorrow? Tomorrow is an uncertain day; how do you know you will have a tomorrow?
Thomas aKempis, 'Imitation of Christ,' 23rd Chapter.
