"The utter uniqueness of the Christian message — the heart of the gospel —
is found in the three words of Christ from the cross, ‘It is finished’ (John 19:30).
The message of every other religious system, without exception, is
predicated on some variation of another three words, which stand starkly
opposed to the gospel’s three words. Religion’s three words are: ‘Get
to work.’ And this is the heart of the bad news behind every approach to
spirituality, enlightenment, or salvation that is not Christian."
