These verses apply directly to the needs of the terminally ill and chronically debilitated. That can never be taken, or given, away. Therefore most gladly I will rather boast in my infirmities, that the power of Christ may rest upon me. Therefore I take pleasure in my infirmities, in reproaches, in needs, in persecutions, in distresses, for Christ's sake. For when I am weak, than I am strong.
Christians grow as they minister to people who are vulnerable and dependent.
Likewise, it requires a special grace to be the one helped. There is no shame in being served. Both experiences are needed in a person's life, and in the life of the Church. If suffering induces loss of dignity, then Jesus Christ himself lost dignity on the cross. For we do not have a High Priest who cannot sympathize with our weaknesses, but was in all points tempted as we are, yet without sin.
