30 There is always a bit of martyrdom in such virtue if we really want to strive day by day for a greater perfection of Christian life. For not only by shedding of blood is the witness of our faith given to God, but also by courageous and constant resistance to the lure of evil, and by the complete and generous dedication of all that we are and have to Him Who is our Creator and Redeemer, and will one day be our never ending joy in heaven.
