Peters is lacking in discernment and is not judging people correctly. I agree 100% with what Refreshed said about him.
Peters may not be saying that he is rich in money, but certainly is saying that he is rich in knowledge of scipture and ability to interpret scripture.
"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 counsel thee to buy of me gold tried in the fire, that thou mayest be rich; and white raiment, that thou mayest be clothed, and that the shame of thy nakedness do not appear; and anoint thine eyes with eyesalve, that thou mayest see."
Revelation 3:17-18 King James Version
