Thomas Brooks emphasizes that man is not inherently born with the light of God in his heart; rather, it is a divine gift that illuminates the soul. This spiritual light allows believers to recognize sin as the greatest evil and God as the ultimate good. It has transformative effects, melting, humbling, warming, quickening, quieting, and gladdening the soul. Without Christ, the soul remains in darkness, but through Him, believers are transformed from darkness to light. The sermon highlights the necessity of God's grace in bringing spiritual enlightenment.

F.B. Meyer emphasizes the importance of the Word of God in the life of a believer, using the story of Jonathan who, amidst the chaos of battle, found strength and enlightenment from tasting honey. He draws a parallel between the sweetness of honey and the nourishing power of Scripture, suggesting that even a small intake can provide significant refreshment and clarity. Meyer warns against complacency after success, urging believers to continually seek nourishment from God's Word, regardless of their circumstances. The sermon highlights that true spiritual vitality comes from a consistent engagement with Scripture, which is essential for both victory and defeat.

John Gill emphasizes the significance of Christ's appearance in human nature, likening it to the light of the morning and the tender grass that springs forth after rain. He explains that Christ's revelation dispels the darkness of sin and ignorance, bringing joy and clarity to believers. Gill further illustrates how Christ's righteous rule is akin to the refreshing light of dawn, promising hope and spiritual growth for His followers. He concludes by encouraging believers to appreciate the light and grace they receive from Christ, who is both their Savior and Ruler. The sermon ultimately calls for gratitude and a commitment to live as children of the light.

John Gill emphasizes the critical importance of the knowledge of God as foundational to true godliness and experimental religion. He argues that without knowledge of God, there can be no genuine worship, obedience, or affection towards Him, as ignorance leads to irreligion and idolatry. Gill illustrates that true knowledge of God is essential for understanding one's own state, the nature of sin, and the way to salvation through Christ. He contrasts the ignorance of the unregenerate with the enlightened understanding of the renewed, who know God, Christ, and the Holy Spirit intimately. Ultimately, Gill asserts that this knowledge is not merely intellectual but must be practical, leading to a life of obedience and communion with God.

T. Austin-Sparks emphasizes the profound significance of spiritual enlightenment through the story of a man born blind, illustrating that his condition was divinely orchestrated to reveal God's works. The sermon highlights that true understanding of Christ comes not from mere doctrine but from a personal, living touch with Him, which opens our spiritual eyes. Sparks draws parallels between the man's blindness and Israel's spiritual state, stressing that enlightenment is a costly journey often requiring a break from tradition. He concludes that the ultimate goal is to know Christ as the Son of God, which transforms our understanding and relationship with Him. The message calls believers to pursue a personal walk with Christ, allowing Him to govern their spiritual lives.
