McGrath points out that the goal of Gateways to Apologetics is to help people see what they could not previously or mistakenly thought they understood about Christianity. He chose several steps to accomplish this goal.
First, explain the gospel using creation, fall, redemption and consummation as hooks. Second, use presuppositional reasoned arguments and show how justified true belief in God makes sense of reality compared to Christianity’s rival worldview. Third, use story, personal testimony and parables in order to communicate the gospel. Fourth, use images of the Exile or Paul’s meaning of adoption in order to point out our human desire to belong and longing for home. Moreover, the use of the Arts helps the apologist relate popular stories as shadows of the gospel message.
The lesson I’ve taken from this chapter is that McGrath is challenging apologists to be creative and culturally sensitive in order to secure an audiences’ attention and interest to more effectively communicate the gospel message.
