What does it mean that God's wisdom is justified?

When Christ states, 'Wisdom is justified of her children' in Matthew 11:19, He highlights that God's wisdom, exemplified through the gospel, is vindicated by those who believe. This signifies that God's plan for salvation, which may seem counterintuitive to the world, is ultimately proven true and effective in the lives of the elect. The wisdom of God declares how He can save sinners while maintaining His justice, illustrating that His ways are higher than ours and affirming our need to humbly trust in His perfect plan for humanity's redemption.
