"The substitution of so-called "practical" preaching for the doctrinal exposition which it has supplanted is the root cause of many of the evil maladies which now afflict the church of God. The reason why there is so little depth, so little intellegence, so little grasp of the fundamental verites [truths] of Christianity, is because so few believers have been established in the faith through hearing the doctrines of grace expounded, and through their own personal study of them. While the soul is unestablished in the doctrine of the Divine Inspiration of the Scriptures--their full and verbal inspiration--there can be no firm foundation for faith to rest upon. While the soul is ignorant of the doctrine of Justification, there can be no real and intelligent assurance of its acceptance in the Beloved. While the soul is unacquainted with the teaching of the Word upon Sanctification, it is open to receive all the errors of Perfectionism or other wrong teachings. And so we might go on right through the entire range of Christian doctrine. It is ignorance of doctrine that has rendered the professing church helpless to cope with the rising tide of infidelity. It is ignorance of doctrine which is mainly responsible for thousands of professing Christians being captivated by the numerous false 'isms' of the day. It is because the time has now arrived when the bulk of our churches "will not endure sound doctrine" (2 Tim. 4:3) that they so readily receive false doctrines. Of course it is true that doctrine, like anything else in Scripture, may be studied from a merely cold intellectual viewpoint, and thus approached, doctrinal teaching and doctrinal study will leave the heart untouched, and will nautrally be "dry" and profitless. But doctrine properly received, doctrined studied with an exercised heart, will ever lead into a deeper knowledge of God and of the unsearchable riches of Christ."
I'd like to add, this is as true today (2012) as it was when Mr. Pink wrote it (1928). I can see exactly what he's talking about in the modern church. We must continue to pray for reformation!
