How do we know that spiritual understanding is a gift from God?

The sermon emphasizes that a man cannot comprehend spiritual truths without divine revelation. As stated in 1 Corinthians 2:14, 'The natural man receiveth not the things of the Spirit of God: for they are foolishness unto him.' This truth illustrates that understanding God and His Word is not attainable through intellect or study alone; it requires the Holy Spirit to open one's heart and mind. This revelation allows believers to see the glory of Christ, as Peter declared when he proclaimed Jesus as the Son of the Living God (Matthew 16:16). Therefore, knowing God is a direct result of His gracious work within us.
