A concise statement capturing the theological difference between Islam and the gospel:
“Broadly the Islamic dictum runs: ‘To know is to do.’ Ignorance, ‘jahilayyah,’ is the problem. Hence ‘huda,’ revelation is the answer. Humans are amenable to law: They can respond to ‘thou shalt’ and heed ‘thou shalt not.’ The New Testament knows that we can know and not do. We have a defiant ability, a recalcitrance that flouts what it quite well understands. It is this perversity which needs redemption. The world is not righted by good advice, but a love that suffers, that bears, and thus only bears away the wrong and can thus forgive. For Christian faith this redemptiveness characterizes the very nature of God as told in ‘the throne of God and of the Lamb.’ This is the ultimate theological issue between the Qur’an and the New Testament, the mosque and the church” (Kenneth Craig, d. 2012 at age 99).
