The purpose of a flashlight is to reveal the true facts of the physical world around us when we are unable to see it because of darkness.
The light reveals what is actually there—it’s a truth revealer.
In 2 Corinthians 4, the Apostle Paul tells us that the light of the gospel reveals the glory of God (v. 4), and that glory is found in the person of Jesus Christ. Do you want to know what God looks like, how he acts, and how he feels? Well, look to the gospel, and see it illuminate the face of Jesus Christ (v. 6).
Without the gospel, our hearts live in darkness, away from the presence of God. We are unable to see who we are and what our true purpose is in this world. We stumble around without the light, trying to find meaning in whatever we can get our hands on…yet nothing is truly clear.
But when the light of the gospel shines in our hearts, it gives us the knowledge of the glory of God in the face of Jesus Christ, and reveals the truth about who God is, who we are, and who we can be if we are in him.
The gospel is beautiful because it shows us who he is, and who he is can be seen in the person of Jesus Christ revealed to us in the Scriptures.
