Modern Christianity has developed a rational apologetic. We engage modern society with rational proofs of God's existence. We provide scientific data to defend divine creation. We have developed logical responses to the questions raised by suffering. All of these presuppose that modern people find the Christian faith intellectually weak. But the problem is not an intellectual problem. The problem is hearts that refuse to live under God's reign. we reject God. It is a relational problem. And if it is a relational problem, it requires a relational apologetic.
What will commend the gospel are lives lived in obedience to the gospel and a community life that reflects God's triune community of love. People will not believe until they are genuinely open to exploring the truth about God. They become open as they see that it is good to know God. And they see that it is good to know God as they see the love of a Christian community. As Francis Schaeffer said: "Our relationship with each other is the criterion the world uses to judge whether our message is truthful. Christian community is the ultimate apologetic.
I don't post this to say that a reasoned defense of the gospel is unnecessary, but I do think that as we display a life that is changed by the gospel, and we are the pleasing "aroma of Christ" in the world, people will be more willing to listen to our reasoned defense.
