The Laodicean church is saying, "I am rich and increased with goods, and have need of nothing." That was her self-estimate. She looked at herself and that is what she saw. She said, "I am rich," which means that she is wealthy in the things of this world.
She is boasting in the face of James 2:5-7,
"Hearken, my beloved brethren, Hath not God chosen the poor of this world rich in faith, and heirs of the kingdom which He hath promised to them that love Him?
But ye have despised the poor. Do not rich men oppress you, and draw you before the judgment seats?
Do not they blaspheme that worthy Name by the which ye are called?"
Now I do NOT suggest that a rich person cannot be Spiritual, but we all know that the Word says very few are. It is the poor that predominate in the body of the true church. Now then, if the church becomes full of wealth, we know only one thing; "Ichabod" has been written over her portals! You can't deny that, for that is the Word.
