In light of the catch, this same tolerance (and even joy) of pain or persecution can be experienced as a Christian. As a Christian, we are not promised a simple or easy life (Luke 9:23-26, 2 Corinthians 11:24-28, 1 Peter 4:12-14). But suffering (or on the opposite end, the pursuit of safety) will not be our primary factor(s) of consideration if our physical and spiritual eyes are set on the greater purpose of pursuing Christ (his fame, kingdom and the spreading of it).
All of a sudden, 2 Corinthians 4:16-18 starts to make a little more sense:
So we do not lose heart. Though our outer self is wasting away, our inner self is being renewed day by day. For this light momentary affliction is preparing for us an eternal weight of glory beyond all comparison, as we look not to the things that are seen but to the things that are unseen. For the things that are seen are transient, but the things that are unseen are eternal.
