Martyn Lloyd-Jones points to the example of peaching in dealing with the personal problems church members face. In pointing to the Puritans as an example of this the Doctor says:
The Puritans are justly famous for their pastoral preaching. They would take up what they called ‘cases of conscience’ and deal with them in their sermons; and as they dealt with the problems they were solving the personal problems of those who were listening to them. That has constantly been my experience. The preaching of the Gospel from the pulpit, applied by the Holy Spirit to the individuals who are listening, has been the means of dealing with personal problems of which I as the preacher knew nothing…1
The Doctor shows us that in this way member care is being done. That the Holy Spirit can and does apply the truth in general to the particular individual through preaching. It is through expositional preaching of the word of God that the church is faithful to the Great Commission command to teach disciples to obey all that Christ has commanded. For all of the commands of Christ are to be found in Scripture.
