How do we know the promise of gradual gospel illumination is true?

The promise of gradual gospel illumination is firmly grounded in the truth of God's Word. Scriptures like John 7:50-53 highlight the progressive revelation given to those who earnestly seek toward Christ. Just as Nicodemus moved from fear to boldness in his understanding and defense of Jesus, so too are we assured that if we follow on to know the Lord, He will reveal more of Himself to us. Additionally, God's faithfulness is emphasized: He who planted the seeds of faith will nurture and strengthen them. Each step taken in faith leads us to a more profound illumination of the Gospel and our place within it, making the journey toward understanding both certain and transformative.
