Jesus says, “You are the light of the world…” (Matt. 5:14), Paul said of the saints, “to the intent that now the [a]manifold wisdom of God might be made known by the church to the [b]principalities and powers in the heavenly places,” (Eph. 3:10).
Yes, every Christian is to be a Revealer, that is one who reveals the good news, the light in the darkness, the church of Christ to the world.
“Therefore I ask that you do not lose heart at my tribulations for you, which is your glory” (Eph. 3:13)
