How do we know that God uses the weak and unqualified for His purposes?

In 1 Corinthians 1:26-29, Paul explains that God has chosen the foolish and weak things of the world to shame the wise and strong, ensuring that no one can boast before Him. This divine selection serves to demonstrate that it is not human wisdom or strength that achieves God's purposes, but rather His power operating through those deemed weak or insignificant. By using the unqualified, God reveals His glory and emphasizes that all success in ministry and life comes solely from Him and not from human ability.
