Note 11 at 1Co 1:27: 1Co 1:26-28 explains things exactly opposite of the way that people think on their own. Carnal people would choose the "cream of the crop" to represent their interests to others. Yet God Almighty does just the opposite.

When we consider things from God's perspective, there really could be no better way. 1Co 1:25 reveals that people at their best are still infinitely lower than God at His worst. Therefore, in the natural, there could never be anyone qualified to accurately represent God.

So God chose the "worst" of mankind and endued them with supernatural power to be His witnesses. This reveals the awesome power of God in a similar way to how the handmade works of true artists or craftspeople testify to their great talent.

Many people could learn to use computers to design art or make things, but it is only the best artisans who can create true masterpieces with only the crudest tools. Likewise, a lesser god could use the brightest and best people to draw others to itself, but only our Lord God Almighty can take the worst people and make the mighty tremble (Ac 24:25). God--not the "tool" He uses--gets all the glory.
