Because thou sayest, I am rich, and increased with goods, and have need of nothing; and knowest not that thou art wretched, and miserable, and poor, and blind, and naked: I am rich - Thou supposest thyself to be in a safe state, perfectly sure of final salvation, because thou hast begun well, and laid the right foundation. It was this most deceitful conviction that cut the nerves of their spiritual diligence; they rested in what they had already received, and seemed to think that once in grace must be still in grace.
Thou art wretched - Ταλαιπωρος· Most wretched. "The word signifies," according to Mintert, "being worn out and fatigued with grievous labors, as they who labor in a stone quarry, or are condemned to the mines." So, instead of being children of God, as they supposed, and infallible heirs of the kingdom, they were, in the sight of God, in the condition of the most abject slaves.
And miserable - Ὁ ελεεινος· Most deplorable, to be pitied by all men.
And poor - Having no spiritual riches, no holiness of heart. Rich and poor are sometimes used by the rabbins to express the righteous and the wicked.
And blind - The eyes of thy understanding being darkened, so that thou dost not see thy state.
And naked - Without the image of God, not clothed with holiness and purity. A more deplorable state in spiritual things can scarcely be imagined than that of this Church. And it is the true picture of many Churches, and of innumerable individuals.
