How do we know the entrance of God's words gives understanding?

Psalm 119:130 states, 'The entrance of thy words giveth light; it giveth understanding unto the simple.' This verse illustrates that true understanding comes from the divine revelation found in God's Word. When His words enter into a believer's heart, they illuminate the mind, allowing one to grasp spiritual truths that cannot be discerned through human wisdom alone. This light not only reveals God's character but also shows us our need for Him, emphasizing the importance of being receptive and humble before His Word.
