How do we know God's wisdom is revealed to us?

The Apostle Paul states in 1 Corinthians 2:10 that it is God who reveals deep truths to us by His Spirit. This means that understanding the mysteries of faith, such as the incarnation and the crucifixion of Christ, is not a product of human reasoning or intellect. The natural man cannot perceive these things, as they are spiritually discerned (1 Corinthians 2:14). Instead, believers gain insight through the illumination of the Spirit, who opens our hearts and minds to comprehend the gospel and the depth of God's grace, which has been ordained since before the foundation of the world.
