Is it sinful not to weep/worry for the sake of the poor of the world, and just give them alms?
Is it sinful to ignore those world news that can only make us anxious and hopeless?
No, it is not sinful. One of the chapters of
The Spiritual Combat by Dom Lorenzo Scupoli is titled, "The Soldier of Christ, Resolved to Fight and Conquer His Enemies,
Must Avoid, As Far As Possible, Anything That Intrudes Upon His Peace of Mind." The author goes on to say, "The countless trials that crowd this life--sickness, wounds, death, the loss of friends and relatives, plagues, war, fire, etc., which men, naturally adverse to suffering, dread--all these, through God's grace, may not only be received submissively from the hand of God, but can become occasions of joy. This is true if we view them as just punishments, inflicted on sinners, or as opportunities given the just to obtain merits."
He continues, "These trials and events occur at the design of our Master; the severest tribulations of this life bring His will to our aid, so that we can march with a calm and tranquil soul.
Any disquiet on our part is displeasing to God. For whatever nature it may be it is always accompanied by some imperfection, and
it always has a tendency towards self-love in one form or another."
