The verse Shane mentioned in communion this morning is an amazing verse as it provides a summary of the gospel:

“For God, who said, “Let light shine out of darkness,” has shone in our hearts to give the light of the knowledge of the glory of God in the face of Jesus Christ.” (2 Cor 4:6)

It was a key verse in the ministry of Jonathan Edwards who preached a famous sermon called, “A Divine and Supernatural Light, Immediately Imparted to the Soul by the Spirit of God, Shown to be both a Scriptural, and Rational Doctrine.” (Don’t you love those long titles!).

Here are two great introductory article by Sam Storms on the passage:

observations on a divine and supernatural light

If you’re more ambitious and want to actually read Edwards sermon yourself you can find it here:

However, I recommend watching John Piper instead as he actually re-preaches the sermon back in 2003 at the Edwards memorial conference!
