How does the preaching of the cross relate to God's pleasure?

In 1 Corinthians 1:21, it is stated that 'it pleased God by the foolishness of preaching to save them that believe.' This indicates that God's method of revealing His grace and salvation is through the proclamation of the Gospel, which may seem foolish to the world but is the power of God unto salvation for believers. The value of preaching lies not in the eloquence of the messenger but in the truth of the message about Christ crucified, which transforms lives and brings about faith in those who are called by God.
