How do we know the doctrine of God's wisdom is true?

The doctrine of God's wisdom is substantiated through Scripture, particularly in Romans 16:25-26, which states that the mystery of the gospel was kept secret since the world began but is now made known for the obedience of faith. This transformation in understanding is not merely intellectual but a spiritual awakening, as God's Spirit reveals the deep things of God to His elect. The wisdom of God, embodied in the person of Christ, is therefore affirmed through both the written Word and the experience of faith within the believers who recognize and embrace this truth.
