There’s a good chance that this customer is a true Christian. Just sayin’ . . . .
GOD HAS CHOSEN THE FOOLISH THINGS OF THE WORLD
For ye see your calling, brethren, how that not many wise men after the flesh, not many mighty, not many noble, are called:
But God hath chosen the foolish things of the world to confound the wise; and God hath chosen the weak things of the world to confound the things which are mighty;
And base things of the world, and things which are despised, hath God chosen, yea, and things which are not, to bring to nought things that are:
That no flesh should glory in His presence.
But of Him are ye in Christ Jesus, who of God is made unto us wisdom, and righteousness, and sanctification, and redemption:
That, according as it is written, He that glorieth, let him glory in the Lord. [1Cor 1:26-31]
