The best evangelical theological work emerges from the delight in the Christian gospel, for the gospel announces a reality which is in itself luminous, persuasive, and infinitely satisfying. That reality is Jesus Christ as he gives himself to be an object for creaturely knowledge, love, and praise. To think evangelically about this one is to think in his presence, under the instruction of his Word and Spirit, and in the fellowship of the saints. And it is to do so with cheerful confidence that his own witness to himself if unimaginably more potent than any theological attempts to run to his defense.
Christology responds to the self-communicative presence of its object in the twofold work of exegesis and dogmatics…Exegesis is served by dogmatics, whose task is to look for systematic connections between the constituent parts of the Christian gospel, and to attempt their orderly and well-proportioned exposition. In particular, dogmatics can help to prevent the distortions of perspective which can be introduced into an account of the faith by, for example, pressure from polemical concerns or excessive regard for extra-theological norms (‘Jesus Christ’ in The Cambridge Companion to Evangelical Theology‘ pp. 60-1).
