“I agree with you, that some accounted evangelical teachers have too much confined themselves to a few leading and favourite topics. I think this a fault, and I believe when it is constantly so the auditories are deprived of much edification and pleasure, which they might receive from a more judicious and comprehensive plan.
The whole Scripture, as it consists of histories, prophecies, doctrines, precepts, promises, exhortations, admonitions, encouragements, and reproofs, is the proper subject of the Gospel ministry.
And every part should in its place and course be attended to, yet so as that, in every compartment we exhibit, Jesus should be the capital figure, in whom the prophecies are fulfilled and the promises established, to whom, in a way of type and emblem, the most important parts of Scripture history have an express reference, and from whom alone we can receive that life, strength, and encouragement, which are necessary to make obedience either pleasing or practicable.”
