The poverty of worldly wealth is that it cannot buy redemption. There is no help for those who put their trust in possessions. In the end, they must surrender all they own and go to the grave as poor as the beasts of the field.
God's children, on the other hand, whether rich or poor by worldly standards, are most prosperous because the grave cannot rob them of their greatest possession, that which possess them. Christ has purchased for them that which cannot be bought with silver or gold. He paid for it with His blood.
