The fact that we are supposed to respect every human life is basic enough for that concept that life is worth living. However poor and miserable, yet when offered to God Almighty, every sacrifice or suffering has an immense value for ultimate salvation. That is the basis for our Lord’s commendation for those who suffer in this world.
“How happy are the poor in spirit; theirs is the kingdom of heaven. Happy the gentle: they shall have the earth for their heritage. Happy those who mourn: they shall be comforted. Happy those who hunger and thirst for what is right: they shall be satisfied. Happy the merciful: they shall have mercy shown them. Happy the pure in heart: they shall see God. Happy the peacemakers: they shall be called sons of God. Happy those who are persecuted in the cause of right: theirs is the kingdom of heaven. Happy are you when people abuse you and persecute you and speak all kinds of calumny against you on my account. Rejoice and be glad, for your reward will be great in heaven; this is how they persecuted the prophets before you” (Mt. 5:3-12).
