To say doctrine doesn't matter, only how you live matters, is itself a doctrine. It's the doctrine of salvation by works.
Timothy KellerThe Cross is not simply a lovely example of sacrificial love. Throwing your life away needlessly is not admirable โ it is wrong. Jesusโ death was only a good example if it was more than an example, if it was something absolutely necessary to rescue us. And it was. Why did Jesus have to die in order to forgive us? There was a debt to be paid โ God himself paid it. There was a penalty to be born โ God himself bore it. Forgiveness is always a form of costly suffering.
Timothy KellerTo preach the gospel is to show people their need for salvation against a backdrop of God's nature and the character of sin, and then present Jesus as the only remedy for what ails them and the world. In my weekly preaching in the worship services I always call people to believe in Christ.
Timothy KellerWhile other worldviews lead us to sit in the midst of lifeโs joys, foreseeing the coming sorrows, Christianity empowers its people to sit in the midst of this worldโs sorrows, tasting the coming joy.
