The New Testament in Three Words

"Adoption through propitiation"

That's J.I. Packer's three-word summary of the New Testament from his classic work, Knowing God.

The Cross: A Manifestation of Love and an Averting of Wrath

From my favorite chapter in Knowing God ("The Heart of the Gospel"):

The wrath of God is as personal, and as potent, as his Love; and, just as the blood-shedding of the Lord Jesus was the direct manifesting of his Father's love toward us, so it was the direct averting of his Father's wrath against us.

--Quoted in J.I. Packer, Knowing God
