We’re tempted to take the doctrine of the Trinity for granted. But there is scarcely any belief unaffected when we get the Trinity wrong. So argue Don Carson, John Piper, and Tim Keller in this discussion recorded at a recent meeting of The Gospel Coalition’s Council. Pull the thread of the Trinity and the universe unravels. Without the Trinity, grace and glory disappear. So does church unity. And we lose a powerful opportunity to share with unbelievers how the Trinity distinguishes the gospel as the source of love for the world.
