The rich man is wise in his own conceit; but the poor that hath understanding searcheth him out.
I have to admit, I imagine it is more difficult for a rich person to live in humility. Jesus Himself said about the rich, "And again I say unto you, It is easier for a camel to go through the eye of a needle, than for a rich man to enter into the kingdom of God.” (Matthew 19:24, KJV).
Someone who is rich can reach out and with minimal effort, have anything they desire IN this world. The thing is, no amount of money can buy you what you really need, and that is our Lord Jesus Christ even the Kingdom of God itself. In relationship with Christ, we are crafted anew with humble hearts. Grace and peace are not for sale, they are gifts from God.
